Re: SBEMU: Sound Blaster emulation on AC97

Posted on Today, 13:02

Here's build with -Os instead of O2 and LTO removed, can you test it? sbemu_Os_NoLTO.zip If it works then there's more investigation needed since for bugs from different build configs. EDIT: another fix trying to fix problem introduced by O2 / LTO: sbemu_mmio_volatile.zip Thanks so much, crazii for …

EDIT: does the 11-Feb build work? there seems no big changes from 09-Feb. After that the O2 and LTO is on, probably causing problems, but are fixed on the 2024.02.18_00-37. EDIT2: I see that SETPVI is used. you can try again without it. SETPVI may be needed by VSBHDA but not needed by SEBEMU, and …

Can you test this temporary build to see if it works? And if it doesn't, you can try /P0 (zero not oh) option to disable MPU port trap to confirm again. SBEMU_fix1.zip EDIT: I also tried to fix the IRQ assignment issue, by just changing the PCI configuration space register only, you can also test …

I added an extra zero there... whoops... but still, the actual spec DOES top out at about the top end of bat hearing. 96khz/24bit, is the minimum requirement for "High definition audio". At that kind of sample rate, having SSMD instructions in play might be kinda nice to have. :P 96khz / 24 bit is …

Did you say that you've gotten 0.9.9c working in SBEMU / VSBHDA? I've tried all manner of settings for both programs, and also in FDSETUP.EXE, and always get a "Failed to detect music card -1" and the same "Failed to detect digital sound card -1" message, and FDOOM refuses to run; the only way to …

Also, I'm experiencing a freeze on all the userbuilds of SBEMU past February or so (since General Midi at port 0x330 was added). The SBEMU program detects all the usual settings, and then just freezes the system. All versions (even back to the first betas posted in Feb / March 2023) previously …

SBAITSO.ZIP Has anyone successfully gotten DR. SBAITSO to work with either SBEMU or VSBHDA? I'm getting either "can't detect Soundblaster settings" or an "Interrupt error" from the program. I think the problem is related to the old 1991 BLASTER.DRV file which it uses, and I can find no updated …

in DOS
Yes, i945 chipset and GMA950 graphics / vbios on Acer Aspire One. Perhaps GMA900 vbios can be hacked to do native 1:1 instead of stretching by default. I looked and can see that no one previously has released such a utility / hack for the EEE701.

in DOS
Thanks for confirming 800x480 display! I found a way to map 1:1 native pixel mode, thereby disabline stretching on my Acer Aspire One, through a custom video BIOS driver from Intel, but of course I don't think that will work for the Eee701. And, it takes up about 64kb of low DOS memory to do so, as …

in DOS
Hope it is useful, that native 640x480 LCD really does look neat playing some old titles. Everything I've read says that the screen on the eee701 is in fact 800x480, not 640x480. Is the screen 4:3 native or is it 16:9? Clarify if you can. I didn't think any netbooks had a 4:3 screen. I have an old …

I have also problem with very low output volume (maybe 10x lower than SBEMU or MPXplay) on my SB Audigy. I though it was just a specific issue of mixer setting of my soundcard type... Did you see this posted on Dos Ain't Dead, posted by Japheth? It's not "halved", it's using kind of a "geometric …

Jazz Jackrabbit definitely has MOD tracker music, not FM synth. I believe you could set the mixing/sampling rate in the settings in the menu, to match with the performance of the system. Maybe you can play with that, to see if you can get the music to work that way? I got Jazz Jackrabbit working …

- Jazz Jackrabbit - I get only some of the FX sounds, like shooting(not all weapons), jumping, bubping(sometimes). No music at all(it's not FM , but PCM, right?) - Tyrian 2 - sounds in menus work, but when the level starts - the game freezes. Did you download the latest pre-release? There was a …

There is a new version of VSBHDA out which now supports 16-bit protected mode games. I successfully tested it on Jazz Jackrabbit and Tyrian 2k on an i5 8th gen Dell laptop with Intel HDA . Thanks to Baron von Riedesel's spectacular efforts, the sound is working and we have another hurdle overcome on …

Both cases are optimizations. Removing the turbo command allowed us to have a fixed value for movement, which enabled further optimizations in P_MovePlayer and G_BuildTiccmd. Removing the nomonsters command lets the maps load a bit faster, something a bit frustrating on slow 386 cpus. I see. Well …

Please try to get it working in DOS. It's the perfect DOS game. I appreciate your efforts and always like to see new 'retro' homebrew stuff. This is great, frenetic action. As has been stated above, you can easily convert the colors to 8-bit and this wouldn't even degrade the quality of the game. …
