LGR Oddware – DOS PC Action Replay: The Ultimate Game Buster

LGR Oddware – DOS PC Action Replay: The Ultimate Game Buster


[jazzy jazz music] [floppy drive sounds] Greetings and welcome to LGR Oddware! Where we’re taking a look
at hardware and software that is odd, forgotten, and obsolete. And this time around
we’ve got this right here the PC Action Replay from Datel for MS-DOS-based PCs from the early 90s. And yeah, this is a little different than the one I covered before that was just like a little
parallel board thingy and some software for Windows 95 this is not that. This is an actual straight up ISA Card that plugs into your computer and manipulates things
on a little deeper level and allows you to cheat at your games and get some save states and slow motion and all sorts of other little things can be manipulated using
a combination of the card and this weird little mouse-looking thing with buttons and switches and stuff. Yeah, what in the world. Let’s take a look at it! So, this is The Ultimate Game Buster the Datel PC Action Replay from late 1993 one of the original models
that sold for 70 pounds in the UK or $90 in the US. It’s an 8-bit ISA Card paired
with a little breakout box they called the Freezer Controller. Huge thanks to Brandon
for loaning me this one for Oddware because
these things have become exceptionally hard to find relative to its later console counterparts or even compared to the latest
PC Action Replay devices like the one I previously
covered on LGR Oddware. But that was a glorified trainer program with a copy protection dongle you plugged into a parallel port whereas this earlier model is a fully fledged PC expansion card for systems running at minimum a 286 processor in MS-DOS version 3.2. More Energy, More Levels,
More Power, More Lives! Action Replay gives you the power to bust your games wide open! Just imagine the power to freeze any program and take total control! Yeah, that certainly would
be a nice change of pace compared to the other PC models I’ve tried those didn’t exactly grant me phenomenal game busting powers so much as they flat-out didn’t work. But anyway, dude! If this does what it says it does like generate infinite cheats, take screenshots, freeze gameplay, enable slow motion,
monitor memory contents and scan for viruses in real time, that’d be pretty fantastic. If anything, the fact that
Datel Electronics themselves advertised it so heavily back in the day, seems to imply a certain
high level of confidence in the product, more so than the crappy parallel port models. This Action Replay received
several board revisions, software updates, box art changes and price drops over the years but the core functionality
remained the same: provide infinite cheat
codes through software and freeze games in
place using the paddle. That latter feature is one that I find highly intriguing since the way it’s
described makes it sound like a kind of save state function that you normally see on emulators. Yet this is an ISA card for MS-DOS PCs so having that kind of functionality through a hardware
add-on is wildly amusing assuming it actually works. Inside the box you get
the Action Replay software on a 3 1/2 inch double-density diskette I don’t know the exact
version of the software but the files are dated
to December of 1993. Then there’s the freezer controller, which looks kinda like a tiny serial mouse minus the ball underneath. The orange button is for activating the Action Replay software itself, allowing you to do
things like enter cheats and freeze whatever’s in memory and this little switch is
for activating slow motion. It connects to the Action Replay card using what appears to be a nine pin serial interface or at least it’s the same kind of D-sub connector on the end. However Datel repeatedly warned users not to plug serial devices into the card or plug the freezer into serial, so, yeah. As for the card itself, it’s a neat little 8-bit ISA card with a handful of Programmable
Array Logic chips, some static RAM, PLCC socketed ROM chip, along with a pin header
and set of DIP switches for the Action Replay’s
ROM address I/O port and IRQ settings. Finally there’s an impressive 50-page spiral-bound instruction manual something that reviewers
at the time criticized for being perhaps a bit too technical to the point of being confusing and yeah, I mean, this gets intense. Even the “quick installation
and setup” section consists of seven pages packed with text and it only gets more
convoluted from there with detailed appendices and things like hexadecimal notation and the basics of 20-bit memory addressing. Even the Q&A troubleshooting section is direct and to the
point with answers like You are making a mistake,
if you give the trainer one wrong piece of
information you could do a thousand passes and you would still not find the right code. Welp, that’s promising. On that note, let’s get the
Ultimate Game Buster installed and for that we’ll be using the venerable LGR Woodgrain 486. Just gonna drop it into a free ISA slot and that’s about it as I’ve already set the I/O port and IRQ address on the card so they won’t conflict with other devices then it is just a matter of
plugging in the freezer paddle again keeping in mind to
plug it into the 9-pin port and not the serial port by accident. And, yeah, that’s about it. Time to freeze and cheat our way to MS-DOS gaming victory. All right, now that we’ve
got the thing installed in the Woodgrain 486 it’s just a matter of getting the software put on the thing through the floppy disk and that is incredibly simple, just a setup program that
guides you through things mostly just making sure that it can see where the card is, where your mouse is, and, you know, addresses
and things like that. Yeah, as long as nothing is conflicting, and it knows where to put stuff on AUTOEXEC.BAT, you’re
ready to start cheatin’. And once the setup was configured and everything’s installed, we restart it and it loads the action
replay COM file here the control program, it
loads it in the memory as a terminate-and-stay-resident
piece of software so it’s always running in the background you can see there all the settings that it got from the setup program and now we can go into
the Action Replay folder and we can look at what’s in here. So it comes with a bunch
of different things, a bunch of pre-configured files and the COM file itself and all we have to do
now is just load a game and start messing around with our little thingy here.
[chuckle of silliness] So it comes with this program here PCMAN And uh [laughs] this is not
the PCMAN I was expecting it is a Pacman clone, but
it’s not the older one it is some other shareware
game I’d never heard of but yeah, anyway, it
mentions in the manual how to figure out this freezing stuff using PCMAN here as an example. So yeah, it’s this, by Simon Constable. Intriguing. Doesn’t appear to have any sound, but yeah, it is just a Pacman game and so as an example of what we can do with this little freezer button, let’s just press it in a spot here press the button, doink! And it takes us over into
the Action Replay menu here. Really it’s just a command line and you can type in all sorts of things it’s just way more advanced than the other PC Action Replays already I mean look at all this stuff. But yeah, we can go ahead
and enter the trainer and this is pretty awesome actually. So we can select the trainer type we can enter some parameters
if we already know them or we can load a parameter table. It does actually come with some already, we’re not gonna do that though. I’m just gonna show you how we can run a trainer, like
create our own parameters. So the trainer type, there’s
really only one that it can do through this particular
part of the program, lives or countable value. So entering a start value. This is the part of the memory that we’re gonna be looking for so right now in the
game we have three lives so we’re just gonna type in three and it’s gonna scan the current memory and see if it finds
anything in the program that we froze using
the little thingy here. It found 4,882 possibilities
and using this function we can just look at the first 10 but this is useless, I mean there’s way too many possibilities. 4,882, man. So we need to narrow that down. So we can exit back to the frozen program and since we’re looking to mess with lives let’s just lose one really quick so that takes us down to just two lives so there’s one and then one you don’t see ’cause you get yeah like an extra. So we got two lives left. Let’s go and park our
little man over here, press the button again, freeze it, and we’re back to the trainer [chuckling of endearment]
I love this process. So the original value is
three, now we have two and it found one location. That went from three to two
since we originally froze it and there you go, we’ve got just the one. This is the Action Replay
parameter, very similar to like where you’d see
in a GameShark code. So this is the code and the address and now it knows that so let’s go to enter parameters and then press “insert” and that inserts the
code that we just found created by looking at the memory and having the program
compare what it knows that’s it. So we can go back to the frozen program. And now, we should never
be able to lose our lives so yeah, look, it just goes right back to the full lives. Lose another one, goes right back. [laughs] So we just created the
infinite lives cheat for this PCMAN game and I can see why they included it because it is, as you can see, very simple to narrow things down. [laughs] and that’s all, man, I mean this is, that’s what this does. In theory this is what
the other Action Replays were supposed to be doing, but it just couldn’t
find the memory addresses for whatever reason. But yeah, I mean look at that, we can lose all the lives
we want, we never will. It’s just gonna keep on looping so you can play this game forever. But let’s not do that, let’s go into some of my other games that I have on here, and we can play some Duke Nukum 1 and see if maybe we can, I dunno, do the same thing. Here’s Duke Nukum, the first one. Spelt with a U, as it was for a time due to potential copyright issues. So yeah, just go into the game here, still have time to watch Oprah. And there we go. So at the moment, we’ve
got eight bars of health because we go full-health, baby, so let’s just, I dunno,
go into the trainer, doink and we can do this,
select the trainer type we’ll do the same thing
we we’re doing with PCMAN but we’re gonna be looking for eight, ’cause we get eight bars of health. And it will scan the memory and let’s see what we find. 8,357 possibilities, ergh. Yeah. So let’s exit to the program again and let us lose a life, or a health. Oh, that kinda hurt. So that’s that, we’re down to seven, doink now we’re gonna look for seven. And it found one. Wow, that was easier than I thought. Huh, okay. So we’ve got literally
just the one location address, parameter, whatever, so there’s that and that, awesome, go in here and insert, dink, dink, and this should be it, I guess. Now, probably have infinite health? [game bleeps] [laugh of satisfaction]
We do! Dude, that’s so cool! Ah dude, that works way better
than I thought it would. Holy crap. [PC speaker beeping] That’s interesting, so
it’s gonna keep it as seven no matter what. I’m assuming there’s a way
to modify that parameter so you can keep it at
eight no matter what, but whatever, the effect is the same. So if I get more health and then, yeah, then it just goes
right back to seven. I dunno, lucky number seven, always got seven health no matter what. [game beeps] That’s pretty darn cool man. So I can just stand on
these spikes forever. So, okay, so we can only
enter two digits at once that kind of limits things, we can’t necessarily alter like the score if we just go out of here we can maybe just look
at some other things let’s see, what can we do here? We can also… “MM”, that’s just monitor. Well, that doesn’t do anything. [keys clack] Memory monitor on, okay. So you have to know the
specific memory address [laughs] I see, what, okay. I can do this, on the other hand. Dump standard EGA/VGA screens to disk. Let’s just do… There you go. I’m assuming it’s gonna save this screen. All right, well let’s get
outta here and let’s try it. [startup chime] Hey. PCX, there it is, and there it is, that is really cool. All right, next order of business, how ’bout we try out one
of the cheat settings that it came with because
I mean it’s got a lot. In fact the Read Me in here set a program here we can
look at what it does come with Legend, Gods, Magic Pockets? Prince of Persia, Whizz
Kid, Pinball Dreams, Unlimited Balls. Crazy Cars Three, Star Control Two, Frontier Elite 2, Ooh. And PCMAN which we’ve already tried oh let’s see, it does say
it does work with Windows by running it in standard mode, huh. Okay, so we got Pinball Dreams going here, let’s try out one of these configuration cheat files that it actually came with. So that is the parameter that
it has for Unlimited Balls. Let’s try that. [keys clack] All right, we’ve got one
ball still of course, and let’s just get a bit of points and see what happens. [arcade music] Okay [laughs] I didn’t mean to do that
badly, but that works. All right we should
still have one ball left if the cheat was working, ah we do! Nice! Hey dude, this action
replay just straight out does the job. That’s awesome. At least with the games
I’m trying it with so far but I mean again, we went like 100% better than we did with those
other Action Replays GameSharks and stuff in the past for PC. let’s try Gods. [boppy beepy music] I just like this music [laughs]. So let’s get into the game, man, I haven’t played this for years in fact I haven’t played
the DOS version much at all. Mostly played this on Amiga. And yeah we have to do this every time in terms of telling it where the table is Because it’s just gonna be
looking in the directory that the game is playing from but yeah, should just be “Gods”. Yeah there we go. So I don’t know which one’s which, let’s have ’em all turned on, whatever. So, cool. It should be there. And now in theory, we
should be an invincible god. Which is great. [gentle explosion] Guess I shouldn’t… Okay well I am still getting hurt, and I lost a life [laugh]. Let’s try again. Okay, yep, I am dying. I was thinking maybe
it’ll just let me live, no, it will not. Even after hitting no lives left, huh. Well what the crap is that? [laughs] it is definitely affecting
something wrong there that high score table was borked. All right, so something
else I wanted to try on here is the SlowMo, or slow motion option which is this little switch on here it’s also configurable by
going in to the command thing but I’ve just got the
game Vet running here, and this runs way too
fast on a 66 Megahertz 46 really anything faster than
like a 16 Megahertz 386. So just shift into first. Oh my goodness, yeah it’s ridiculous. So if we engage the slow motion, [engine drones in slow motion] Ah, turn off the sound. Yeah, ah, I don’t think
this is doing anything. Hmm, maybe the system’s just too fast for it to do anything on that kinda… One percent, wait, one percent slowdown or one percent of the speed? [keys clack] that’s oddly stated. 99%, so that should be extremely slow if that is how it works. Okay, that’s definitely doing something so it’s backwards from like how it is using the program SlowMo or MoSlow in DOS and it’s not working very well in fact it’s just very choppy may as well just use the turbo buttons on the computer, yeah
see here is turbo engaged on the 46, like the actual hardware itself [laughs] this is what it should be doing it is without turbo, and now full speed
again, running over nuns, and then back on turbo, without turbo, yeah, the actual turbo switch, using something else makes more sense than the little switch on here, so. Okay well, that doesn’t work very great but it does work [laughs]. How ’bout this virus scan,
what the hell is that… Okay, it’s an actual virus scanner. Why not? Value for your money I s’pose, don’t know what it’s using for it’s database of viruses, but cool. Here’s one I was wanting to try, freezing the memory, that’s freeze the entire contents of memory to disk. Kinda sounds like a
save state type of thing so looks like we can use this
to just save it to a file. Intriguing. So I’ve got Crystal Caves
running in the background here let’s see if it’ll do that. So this is what I have running
in Crystal Caves right here just the very beginning
of the first level, the first episode. Well, first level, depending
on which level you choose but first one I normally choose. And we’ll just shoot the air and die. [laughs] Pouf, I am dead. So yeah, lost a life, totally dead. So let’s see if we can un-freeze that and just go right back to where we were. I believe that’s how this works. So yeah, “unfrz cc” Actually it’ll be C-A replay CC something, then this, unfreezing from this will overwrite the current
contents of RAM, yes. Go ahead, whoa. [laughs] How scary. Oh, dude! Totally works! Ah, that is rad, you got save states [laughs] on a real DOS computer. Dude, that is cool, ah that is cool. This device is so cool! Dude, I love the fact
that this actually works exactly what you want from Oddware, it is odd, and it’s obscure, and obsolete and all these things, but man, it works and it
is actually functional for something that is 30 years old, 25 years old, whatever, you
know, old hardware for PCs. [keys clack] Ah, look at all these things, yeah, dude, there’s just so much you
can do with this card, wow, yeah, this is great. I am so glad we got to experience this especially with how badly
the other Action Replays ended up working out, oh man. Well, that’s about it for
the Ultimate Game Buster here at least for this video, yeah
this is mighty impressive, this PC Action Replay
works so much better than the other PC Action Replay
that I looked at before, I mean, that didn’t have this
kind of a hardware solution it had a parallel port dongle,
but that was really just for copy protection as far as I could tell and the software wasn’t
nearly as straightforward as the trainer this comes with and this just gives you way more options in terms of generating your own cheats and sniffing through memory and messing around with
dumping what’s in the memory and opening it back up again, like there’s so many things that you could potentially do with this and that is just really cool. So thank you very much again to Brandon for sending this my way so I could look at it here
with you on LGR Oddware, maybe I can get another one
of these, like for myself in the future, that’d be really cool but I’m just happy I got the opportunity to mess around with this one. So yeah, thanks for watching. And if you like this, then why
not check out that other one that I covered in the past,
or the GameShark variant neither one of ’em worked, spoiler alert, but eh, I tried. And if you like to see me
trying with odd hardware and software than this is the show for you and there are new videos
of all kinds going up each week here on LGR and once again, thank you for watching.

100 thoughts on “LGR Oddware – DOS PC Action Replay: The Ultimate Game Buster

  1. If you acquire one of your own and think there's more content to show off here, please upload a part two to this! As someone who didn't grow up during the DOS era, this video was incredibly satisfying and educational to understanding how games, memory, and action replays work!

  2. HOLLY MOLLY, I remember 'Action Reply Cartidges' for my old C64 back in the day, AMAZING, Question, is their anything like this for PC's with all the latest Games Out Now? I'd buy one in a heart beat!!!

  3. That thing is actually quite impressive. I would certainly have bought it back in the day, if I even knew it existed. Nice video, Clint.

  4. I have to think someone could reproduce this board using the roms and software. Even if the chips are unavailable and it can't be exactly this board its just a nice system for peek and poke.

  5. Had something like this for the original PS1, cartridge that plugged in the back. Felt like such a HaX0R finding infinite ammo and lived for quake 2. haha.

  6. you probably already suspect this but when you are playing duke and your lives are stuck at "7" instead of 8, it is because it is actually set to 8 but it only updates when you lose a life, you can get some interesting results increasing lives etc higher than the original number, everything from graphical glitches to instant death due to the game not knowing how to handle a number outside of what it is expecting

  7. Very similar to Amiga version. I've only emulated Action Replay III on WinUAE. Never had real one. I ripped some samples and music modules in emulation and it worked just fine if you knew what you were doing. If I'm correct my Amiga MIDI interface is made by Datel too. MIDI Master for A500 and 2000. Works on every Amiga tho.

  8. Very cool! Though I assume it is indeed for DOS only as it wouldn't work with the multiple software layers running in Windows?

  9. This seems like something that would have been incredibly useful for magazines and software reviewers at the time. Being able to take perfect screenshots without issue?

  10. That memory search functionality is also provided by a software called "Game Wizard". Worked pretty well for me back in ye olde days.

  11. Kinda reminds me of Gameshark for PS1. It had a button on it that took me to special screen like the one in the video and allowed me to create my own codes. That's pretty much what I did for infinite Zenny in Mega man legends

  12. Duke Nukem: You lost a health bar
    Action replay: Aa aa aaAAa you need to the magic password Aa aa aaAAa Aaaaaaaaaaaaaaaaaaaa aaAAa you need the magic password.
    LGR 😀

  13. This is WAAAAY too obtuse for a regular consumer, especially for a 90's kid interested in getting infinite lives in Commander Keen or whatever; BUT, this thing has TONS of potential for programming and debugging, pretty darn impressive, especially for the time this was made!

  14. So this thing works exactly like Cheat Engine does today. You scan for a value, raise or lower it ingame, scan for the new value, find which you want to adjust and adjust accordingly and a bunch more stuff.

  15. got to use a 45 year old computer. I do not think there are not many of them left. there ware ways to play very old games on 2020 computers there is no floppy drive any more. however there is a web sight GOG . com that stands for GOOD OLD GAMES Yep that is what GOG stands for. I am not making that one up. There is a old game INTERSTATE 76 its not as old as PACMAN INTERSTATE 76 is the first OPEN WORLD video game. just like GTRAND THEFT AUTO IV and GRAND THEFT AUTO V there grass roots come from INTERSTANTE 76 . it works on WINDOWA 95 LUCKY it did work on WINDOWS 98 .

  16. I like to have a more modern version of that for my GAMING NOTEBOOK its got a Z370 CHIP SET and a INTEL CORE i9 9900K. it dose not have ISA slot. it died along with the PS2 port. NO NOT PLAYSTATION 2 . Oh man that very same PS2 port is on my MSI X99 GAMING GODLIKE motherboard.; NO ONE UESED IT. why put something on one will never use,? any way X99 motherboards did die off the market,. it was replaced with the X299 motherboards . I think its coming to the end of its life. Why? AMD come up with X570 motherboards that got the next gen PCI EXPRESS SLOT known as PCIe 4.0 and RYZEN 3000 series CPUs however there 10 year old graphic cards had been mod to PCIe 4.0 5700XT its called,. its crap there are video games that do not work on 5700 XT graphic card I am waiting for NVIDIA and INTEL to catch up.

  17. @LGR
    If you like this, you should check out a Final Cartridge III module for the C64 from around 1986. You'll freak out over what it can do. Oh yeah, it can still be found for cheap and usually comes with the C64 mouse. Imho te greatest Hardware module ever created.

  18. My first proper PC I bought myself was a Gateway DX2-66 with that same monitor imported from the US. It was a lovely machine. I remember how blown away I was at how fast it ran Novalogic Voxel games.

  19. I haven’t seen this video yet but when I was a child I managed to buy the action Replay cartridge for the Super Nintendo and it was awesome fun. Playing Street Fighter was cool. You could jump up in the air and do fireballs and speed the game up or slow it down etc.

  20. Does this guy have made video about the addittional buttons of keyboards, for example logitech mx-500 (?) If I remember right might have been mx-800. That think had literall shitton of buttons, that I have not seen anyone used… It was not the funniest, but the biggest of kinda normal ones…

  21. This is amazingly cool! I have to find one for myself!

    Could you maybe do something on the earliest CD-ROM drives of PC history? The ones that required their own special interfaces? I would like to learn more about them.

  22. It should be possible to implement this entirely in software. TSR + program. Does anybody know of any software-only alternative?

  23. While the ability to dump the contents of RAM to the hard drive was a feature unique to the PC release, my understanding is that most Action Replay units for consoles performed similarly to this, and could be used to halt programs and scan the contents of RAM to figure out what values would control lives, coins, etc. Comments about the manual notwithstanding, I think the fact that action replay stuff is more directly expressive of the contents of RAM goes a long way to understanding how software works, and I think it's much more intuitive than the encoded cheats that the Game Genie used. Of course as you note, these days you may as well be using Cheat Engine to do this.

  24. I wonder if there are people out there on the internet that have figured out codes/cheats for games and have them written somewhere, using this hardware

  25. It's amaze-balls that these guys are still around, bought an Action Replay for the Nintendo Switch when it first came out.
    https://www.codejunkies.com/Products/PowerSaves-for-Amiibo__EF001200.aspx

  26. Interesting. Address finding is still done much the same way via emulators, except now besides cheats and trainers we have tool assisted speedruns and Retro Achievements. I would have loved this thing back in the day. Never heard of it.

  27. 14:00 absolutely no codes required for Star Control 2.Just keep a diary.

    Now Nomad, I've love to hack that game with this.

  28. I remember that artwork, the half knight half skull robot thing and thinking it was so cool when I was 8 here in UK. Never did get it though, wish I did now I’d send it to you! Thanks for the nostalgia LGR!

  29. I thought that Gateway monitor looked familiar, looks like it's some kind of rebadge of the Mitsubishi DIamondPro 21TX, is that a trinitron tubed display?

  30. I miss the days when I was around 7 Years Old. Me and my Brother had 100's of Amiga Games with Trainers built in 🙂 It was Awesome!

  31. I used the Action Replay for SNES quite heavily back in the days (still have my original cart). I used it especially for RPG's like Chrono Trigger and Final Fantasy, in Chrono Trigger I set up an infinite energy (life) cheat for all my characters. When I got to the first fight with Lavos I had no idea you were supposed to lose that battle and I ended up fighting him to his end and got one of the secret endings. On Final Fantasy VI (Final Fantasy 3 in the US) I noticed that the Action Replay cart could wipe out the saves on the cart if you were unlucky!

  32. Most likely used as an aid for creating software cheats, trainers, patches to modify games and of course cracks to patch out copy protection and unlock shareware to full versions for software that included the full game but required a code or password to access it all.

  33. I was so happy so see this video — especially after the disappointment of the previous Action Replay prodcuts you featured. I had a few Action Replay cartridges for the Amiga 500 and Commodore 64, over the years, and they were Awesome! A friend and I originally saw the C64 Action Reply cartridge advertised in a UK Commodore 64 magazine. We had never heard of it or Datel Electronics. They were the new kids on the block, taking on more the established companies. The product sounded almost too good to be true, and the price was also very competitive. We deciced to take a chance and import one. After a painfuilly long wait, it finally arrived! Wow, was it amazing! It did everything it promised. Freeze games and make "backups" of them. Save states, screenshots, find and create cheats, rip and modify sprtes, rip and save music (SID tunes) from games, disable sprite collision (cheat to stop you getting killed by enemy sprites) and a whole lot more. And the number one feature for me: the Fast Loader.

    The C64 had a painfully slow disk drive, and some pretty arcane disk commands. It really was the system's greatest downfall. But this cartridge changed all of that. You got a fast loader which allowed you to use the function keys as hotkeys to list disk directories, load and run games and more. And the difference was huge! In later versions of Action Reply It loaded games 10 to 20 times faster than standard – several times faster than the famed Expyx Fast Loader cartridge. Loading a game went from taking minutes, to just seconds. It really was a game changer for the aging C64! If you still have a C64 you really should try it, or its spiritual sucessor the Retro Replay.

    Or even better, there is an awesome disk drive replacement cartridge called the 1541 Ultimate II+ that allows you to emulate the old 1541 disk drive and run many such classic cartidges as well, so you can quickly and conveniently run disk images at the incredible speed afforded by the Action Replay cartridges, and have all their other features too. What a win. 🙂

  34. It's similar to how you find cheat codes in emulators. You don't need a 50 page manual to understand you are searching for the locations of a certain value and then monitoring the changes to pinpoint the actual location. Maybe they could have used illustrations or cartoons to explain to non-techies how computer memory works. I like the screen shot feature though, it's very rare that DOS games have a screen shot feature. Yeah you can take screen shots in Windows, but back then, if you are using MS-DOS or in DOS mode, it's hard to take screenshots, I actually don't know how aside from taking photos from a camera lol.

  35. If you wanted to find the value to keep 8 health in "Duke Nukum" (lol) you could have scanned for the value of 7 when you had lost a health as your starting point, picked up a health replenishing item, and then look for the value of 8 for your second scan.

    So essentially what you did, just backwards.

  36. I bought one of these back in the early 90s. Mine must be a later software version. Mine included XT's, and i have it in my 8-bit Amstrad PC3086. It used a colour menu which looked similar to the megatrends BIOS screens of the day.
