Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!

Posted on 2023-01-20, 12:51

Today I installed a SBPro compatible sound card and decided to test it in Fdoom 0.9.3. As expected, the channels were reversed. I tried to run Fdoom -reverseStereo and did not find any difference, the channels are also reversed. Why is that? Which card model is it? Also what configuration (BLASTER …

Re: Injecting files into a running PCem/86Box machine

in PC Emulation
The local folder CD-ROM in 86box is near to a perfect solution, it basically works similar to a read-only shared folder. No need to update anything, just copy files between the CD mapped drive and the hard disk drive via DOS. With a simple batch script you can copy the whole folder into the hard …

Glad to hear you like the new AudioCD feature! This is the best way of playing Doom if you don't own a Roland SC-55. I've created an AudioCD for Doom and another for Doom 2 using the audio captures of this website http://sc55.duke4.net/games.php#doom, the result is truly astounding. By the way I'm …

Strange, The MSCDEX is working the first time but reports no AudioCD tracks available, and the second time it reports properly the number of tracks. Maybe there is some incompatibility with the VIDE-CDD driver as @Gmlb256 said, or maybe the driver needs some delay to properly initialize the drive ( …

@Darmok Great to hear that! @theelf New test executable, now it writes the MSCDEX initialization process into the file "fdoom.log" with all the steps done. It should show something like this: CD_Init CD_CdromInstalled: Alloc DOS MEM CD_CdromInstalled: Prepare registers CD_CdromInstalled: Call 0x2F …

Great, at least CD track changes are working. Does the first time AudioCD initialization error happen on both MSCDEX and SHSUCDX? I'll upload a more verbose test release to check were it fails. I'm guessing there is an error in the MSCDEX initialization process, but only happening on real hardware …

I've uploaded a new executable, it should fix Hercules automap border errors and the change between AudioCD tracks ingame. I've started testing on 86box since DosBox-X is not good enough (again, sigh...). @theelf What IDE CD-ROM driver and CD drive do you have? https://github.com/viti95/FastDoom/ …

I've tested in 86box and F1 key press on Hercules automap mode doesn't crash for me, but in fact there is a bug on rendering with screen border and Hercules automap enabled, it doesn't get refreshed as it should, which I'll fix. Thanks for finding it out. I wonder why it crashes on F1 key press for …

I've remapped the AudioCD tracks for Doom, Ultimate Doom, Doom II, TNT and Plutonia following the DoomWiki details, all of them should fit on regular 80 minute CDs. Also have fixed the non-cleared Hercules VRAM on exit (I still have to check the FPS counter issue). This night I'll upload another …

I think AudioCD for Doom/Doom2 is perfectly fine doing music remapping and adjusting length of tracks. I think the main issue is track looping, on software is instantaneous (checked 35 times per second), but I guess CD-ROM drives will require a bit of time to seek to the start of the song. It's a …
