I don't get it, why would you tinker with a pc you want to keep factory original unless it's broken?

@joakim: Are the parts you replace broken? Do the new parts generally improve the system?

1990's point-and-click/adventure games are always a dilemma for me. Your Lucasfilm/arts, your Sierra Quests, etc. In one sense I love them. I spent many many formative hours walking through them as a teen in the 90s. Had a lot of great laughs. Loved the graphics and music. In short, was highly …

Using interrupt 15h works well enough for me. Example: https://github.com/PeterSwinkels/Balls/blob/main/BALLS.BAS

I found something that might work using INT 0x15, 0x86. Thank you Kalle! https://www.vbforums.com/showthread.php?89292 … l=1#post5531376 Once I modify a game I wrote or write new one I can really test this solution.

@Kalle: I will look at the file. Thanks. @ripsaw8080: It depends on what exactly I would need. @Ringding : I could do that, but won't that mess up the time/date?

I will look into that. I could use CALL ABSOLUTE or QB45 library function INTERRUPT.

Oh, which game were you trying to extract sprites from?

I already asked this question at https://www.vbforums.com/editpost.php?p=5531200&do=editpost but I get the feeling I may have more success here. (Given this relates to MS-DOS programming and older hardware.) Whenever I needed a delay in my QBasic/QB45 program I would use a simple delay based on the …

@bloodycactus: I added the missing lines, it works as expected now.

Okay, I will patch the code once I have access to my own pc and check again. 😀

I did not modify your code in any way. I just assembled it using Nasm. Okay, I will look into 0x49 when I have the time.

Image1.png I see your 475 byte tsr scaffold (myTSR) is using over 4 kb - is it supposed to be using that much? Also, I haven't (yet?) added any memory management to my mmdmptsr.com program, but according to MS-DOS it's not taking up all memory as you can see in the screenshot. And yes, this is …
Re: How do I know if a game is MSDOS?

Uh, I believe *.com files are almost always nothing but DOS executables. As for *.exe files, try and see if they will run in DOSBox. Just to better understand your problem, what operating system are you using and what issue are you are running into that brought up this question?

Okay, for anyone who cares: I finally got around to making a few updates such as adding messages to the program. Link: https://github.com/PeterSwinkels/Memory-Dumpi … -TSR-for-MS-DOS

Come to think of it, the CPU and video card aren’t the only important things. After getting to hear a few of my old favorites using a soundcard I wish our old 80386 had had one. A lot of games would have been even more fun to play.

Yeah, I think Cybersphere qualifies, looks and sounds nice for a DOS game. :-) I see noone mention the original two DOOM episodes. Because they run like ass on 486 PCs except DX4s. I played Doom 1 on an DX33 and loved it, but let's be honest, it plays like ass. Nah, it runs well on a VLB DX2-66. I …

Okay, I see your code is a lot more advanced than I had expected. Here's a list of interrupts you appear to be using which I never used: int 21,48 - allocate memory int 21,49 - free allocated memory int 21,4a - modify allocated memory block (setlblock) int 21,9 - I see your tsr communicates with the …

Yes, and those still had relatively few bugs. Quest for Glory IV was more modern and an excellent game story and puzzle wise. It was also an example of a bug-ridden Sierra game just about as bad it could get.
