Stripped the code, but it is still crap. I also really dislike the IDA 5.0 freeware version, have to dig out one of the old versions when at home...

Thanks! Will try that. I don't remeber having to do that ever with the old versions of IDA Pro...

If I'd be able to decompress it properly I could maybe make a 32bit color mode patch... :'(

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 probably didn't worry too much about graceful termination for a problem they likely didn't have. I understood …

Well. IDA Pro tells you that the TSR does something to INT 15h and 1Ch: public start start proc near jmp short loc_10116 loc_10116: push cs pop ds mov ax, 351Ch int 21h ; DOS - 2+ - GET INTERRUPT VECTOR ; AL = interrupt number ; Return: ES:BX = value of interrupt vector mov word_10111, bx mov word_ …

Hmmm. Sorry then. It seems I screwed up there earlier... 😒 What about the "-24" crash? Is this the demos fault or is it DOSBox that b0rks out, or the S3 card, or whatnot? I wasn't able to disassemble the code. It seems to use an unknown packer and IDA Pro doesn't like it...

I think there's some confusion here. Maybe I screwed up some information too... The demo crashes with the -24 switch. I does NOT crash without it. I tried what you said and the demo runs ok. It uses fake highcolor mode in the Minnie mouse part obviously and all frames are now of the same size. What …

Please tell me the exact configuration I should try... w or w/o -24, vgaonly or svga_s3 and so on?
Re: Unsupported video mode in demo
Posted on 2013-04-12, 11:18
Makes sense only with svga_s3 I guess: with the -24 switch it says "Using VESA 2.0 Truecolor mode" w/o it say "You can use the -24 switch" bla...

With vgaonly it runs all the way through, regardless of the "-24" switch (makes sense) and the Minnie Mouse part uses the fake highcolor mode.

raer Can you also verify this: When you start the game it displays some text lines about the testings it did. Depending on whether you use -24 switch or not there is a different message there: it either says it runs in true color or that you can switch to true color with -24 switch. What message …

The mode must be 640x400. That's what DOSBox captures when you create a video of that Minnie Mouse part. @s3freak: Nice! How does the part look with your patch? Is it still some fake RGB-scanlines or is it just regular 320x200? EDIT: Attached my dosbox.conf
Re: Unsupported video mode in demo
Posted on 2013-04-11, 17:49
Hmmm. Not sure. In the part that crashes it seems to switch to a 640x480 mode and then use fake highcolor anyways... The solution works for me so that's ok... Thanks for the help y'all!!!
Re: Unsupported video mode in demo
Posted on 2013-04-11, 16:09
WTF! That worked. Thanks! Btw. I don't know if the S3 should have the appropriate mode, but VESA should have 320x200*24Bit

The part seems to run too fast. If you set the cycles lower you'll see the logo stretching more or less correctly. Maybe the overlay is not synched to vsync?... For me it crashes both with and w/o the "-24" parameter.

Hi All. I have this Ms-Dos demo here that exits with an unsupported video mode after some time (~2min). I tried "svga_s3" and "vesa_nolfb". Is the mode missing in DOSBox or is the demo doing something weird? Best Regards, Kim EDIT: The DOSBox debugger tells me: 526975038: INT10:writechar used …
