Well some news about the Apogee Sound System GUS code, I've asked Jim Dosé if there was any source code available that uses hardware mixing instead of software mixing: 2023-01-31 10_52_21-Victor Nieto en Twitter_ _Hi @jim_dose ! We've found out that the Apogee Sound S.png Sadly there is no source …

The released source code of the Apogee Sound System is from 1996, take a look at the readme: https://github.com/videogamepreservation/rott … UBLIC/NOTES.TXT

Yeah there is a limitation with the Apogee Sound System, it doesn't like GUS devices with IRQ higher than 7. I've never looked into why exists this limitation, but the developers did it anyway: GetUltraCfg(&os); if (os.forced_gf1_irq > 7) { return (GUS_Error); } Even more they disabled the hardware …

Just tested with OPTI930, everything is ok, -reverseStereo option reverses the channels correctly. I admire how quickly you solve problems. Thank you. Great to hear it's working now. I've been developing this project for so long that even on vacation without my laptop I already knew how to solve …

I guess the issue with -reverseStereo is that it forces to reverse the stereo setup, but SBpro code also forces it, so it's basically doing nothing. I'll modify the -reverseStereo option so it disables stereo reverse on SBpro cards.

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 …

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 …

I've discovered a better way, using MSCDEX with 86box CD emulation. If you map a Windows folder to a 86box CD drive, the files are always updated, so no need to mount/unmount the drive. This way I can copy files very fast and without having to create images nor something like that.

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 …

I've uploaded another executable with an updated MSCDEX initializacion (similar to Hexen). Can you try it again? https://github.com/viti95/FastDoom/releases/d … oom_0.9.3a7.zip

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 …

Oops that shouldn't happen 😅. I think I'll write the log to a file and check the whole process better. This weekend I'll be very busy, but will try to get it as soon as possible.

More verbose testing release https://github.com/viti95/FastDoom/releases/d … oom_0.9.3a5.zip. It doesn't change how MSCDEX is initialized but will show a more detailed message on what failed.

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 …
Re: Fastest/Best Pentium 4?
Posted on 2023-01-13, 09:05
I'd say the fastest NetBurst CPU is the Xeon 5080. Socket 771, 3.73 GHz, two cores and SMT (that's four threads!). Put two of these on a multicpu motherboard and you will have 4 cores and 8 threads.
