I've updated the testing release with fixes for Doom2, TNT and Plutonia audio-cd music tracks (now they start as they should) and fix the Hercules automap feature to properly revert the Hercules card to text mode. https://github.com/viti95/FastDoom/releases/d … oom_0.9.3a2.zip

Ok I'll remap Doom 2 (and also TNT and Plutonia) music, so the first 32 tracks won't be empty on the AudioCD. @theelf have you been able to test this build on real hardware? @Darmok yeah for sure, the code to revert the Hercules from graphics mode to text mode is already done, just forgot to call it …

Mus_e1m1 is track 1, mus_e1m2 is track 2 and so on. I guess Doom 2 music works in the same way (e1m1 is map01, e1m2 is map02...) but cannot affirm 100% right now. I'll try to look at it, with the moving thing is hard to get free time for anything 😅

Good idea, FastDoom is able to use the ATI Small Wonder 640x200 and 16 colors mode, but is very slow because the massive 8-bit ISA bus bottleneck. Maybe it's possible to use the 132-character text mode (132x25 or 132x44) to generate more resolution with composite while providing more colors. The …

I have encountered two bugs with the sound of FastDoom. On my 486 with an AWE64, I only have digital sound the first time. Every launch after that the digital sound doesn't work. I have to run a different game (the original DOOM2.EXE for example) to get digital sound back in FastDoom, but only once …

Uhh interesting, maybe there is a desync issue in 0.9.2. What game are you testing, Doom or Ultimate Doom? EDIT: Indeed is a bug in the latest release, will fix it and release a bugfix version.

How much RAM do you have in your 486? Cirrus Logic cards cannot map it's VRAM above the first 16Mb, so it's required to have less than 16Mb to be able to map the linear framebuffer of the video card. I use mine with 12Mb of RAM (8+4), as SDD refuses to enable the LFB with 16Mb. Maybe that's the …

I've done some benchmarking and the fastest mode is VBE2 Direct, followed by 13h and lastly Mode Y, although I haven't compared the latest release. Use VBE2 Direct mode whenever possible, it uses the Heretic rendering functions and writes directly on VRAM. It's the best combination possible, it …

I've rebuilt and reuploaded the executables, those are working on my 486 without music/sound issues.

I've seen a similar behaviour on Trident cards when there is a palette change without waiting for the VSync. I'm pretty sure it's the same issue, nothing you can do about as is a problem on the video chip design.

While developing optimizations for Potato mode i've just discovered a bug that I think it hasn't been documented and exists since... 1994 (!!) It just happens that Heretic has a rendering bug on R_DrawSpan (which is ASM optimized and it's much faster compared to Doom R_DrawSpan). It basically …
