Re: DOSBox DOS timer overrun bug

Posted on 2013-04-19, 16:46

Midnight rollover is implemented in SVN. Setting the time with INT 21/2D is intentionally blocked in DOSBox; but as you've noticed it is possible to change the BIOS timer ticks directly, and it can also be done with INT 1A/01. INT 21/2D in SVN allows the time to temporarily be set to 00:00:00 …

To use IDA, first make sure the version you have supports linear executables, because not all free versions do. Then you'll need to strip the linear executable portion out of the decompressed executable, because the extender portion confuses IDA. The idea is to keep everything starting from the LE …

Later on, I found that boot to real DOS can solve this problem. Set cycles to about 30000 and don't press "Alt-F12" when running it. "Toontown -24" works. I assure you that booting DOS is not going to make 24-bit color modes magically appear in DOSBox's S3/VESA implementation... FYI, the demo will …

What about the "-24" crash? Is this the demos fault or is it DOSBox that b0rks out, or the S3 card, or whatnot? I explained why the demo terminates with an error when the -24 switch is used in my first comment. The ungraceful nature of the termination appears to be the demo's fault, but the authors …

Mode 13h is normally 320x200, double width, double height, 70 fps. The "Kolor super demo" uses register-tweaked mode 13h at 320x400, double width, normal height, 70 fps. The issue might be a misreading of the display timing due to the screen resize delay. If anyone who has the issue would like to …

I guess the crashy part is where there's a pic of Minnie Mouse with the caption "Kolor super demo"? I can't induce a crash there when I don't use the -24 switch, and I've tried all output= options and fixed / limited cycles... it just works every time. I don't view it as a blessing when I can't …

Hmm, maybe some timing issue, because the demo runs to completion on my system with default settings in DOSBox 0.74 and SVN (as long as the -24 switch is not used). This program is to solve another game's problem and I am not the author. It looks similar to a workaround I made for Sokoban Revenge, …

The default "faked" hi-color on mode 13h has no trouble, it's only when you run the demo with a -24 parameter for TrueColor that you get the error message. It can't find a VESA mode that is 320x200 with 24-bit color. The TrueColor VESA modes in DOSBox report 32 bits per pixel through INT 10h/4F01h, …

Re: svn 3616 breaks LBA2

Posted on 2013-04-09, 22:18

Trying to change the current directory using a "C:" path spec with INT 21/3B returns error 3 (path not found) in real DOS, so revision 3616 (along with revision 3659) is producing the intended DOS-compatible behavior. Perhaps the GoG version of the game is in some way relying on the previous, …

It's a known issue that using the adlib for digitized sound doesn't work well in DOSBox. FM synthesis is already pretty heavy CPU-wise, and the sampling rate needed for digitized stuff would make the load even heavier. Hal-9000 tried an experiment to offload the digitized sound from the adlib to the …
