Re: SBEMU: Sound Blaster emulation on AC97

Are we supposed to be using "LH" when loading hdpmi and sbemu? I haven't been. That might be related to your issues? Also, did you set the right irq and dma for Doom using setup.exe? Quake and Wolfenstein just use your "Set Blaster" environment variable, but Doom does not. You also might try using …

Here's early test edition of SBEMU with new DPMI (let's call it 1.1-alpha1 release candidate 1 for now), which includes the new DPMI I'm working intensively on for more than 2 months. It's been tested by veelstekel for couple of days but now he is temporarily unavailable, so I post the zip here for …

Testing 10b4. 1. Fast Tracker v2.12 It works, but the soundblaster is not recognized. 2. Scream Tracker v3.21 Doesn’t work, it says “initialization...” and hangs. 3. Impulse Tracker v2.15 Works great. 4. CHASM - The Rift Doesn't start. But if you first run the command hdpmi32i.exe -d, it starts and …

There's no big changes but some tiny ones: * skip software FM emulation if HW FM is used. * HDA: potential bugfix * compatibility fix on high DMA. BTW the release is originally tagged with "UserBuild_2024.05.02_04_31" and I renamed it to beta4, because my VPN is again f**ked up by the GFW (still …

Very interesting. having seen a bunch of software renderer but this is the first time I've ever seen a living one for DOS.

Yes ,SBEMU.EXE /I7 made it hang. I was fiddling around with /I9 and /I5 and when I set it to /I7 the PC crashed. So what's the IRQ it uses when it works? not 7 anymore? that's not expected. BTW war2 works fine on my P3 laptop, and the setup runs fine on a more modern one. There're still too many …

No blaster set at the moment. I read in the docs that SBEMU sets this once loaded? Yes. So what were the parameters used before, that cause your system hang? /I7? Yes ,SBEMU.EXE /I7 made it hang. I was fiddling around with /I9 and /I5 and when I set it to /I7 the PC crashed. So what's the IRQ it …

EDIT: some breaktrough. Apparently if I set the interrupt to 7 (the default it crashes on my system). Weird. Anyway I removed the switch and now it works. Weird, the default value is still 7 if not set. did you set BLASTER before installing SBEMU? what's the settings? T6 probably? and Any extra …

OPL emulation at port 3: enabled. The port 3 is wrong and confusing, I'll check the code first. EDIT: OK its probably a typo and the message is hard coded to be 388. You may want to try with JEMMEX installed, and add /P0 for SBEMU, and /I5 to change IRQ to see what happens. there'll be logs on next …

This morning I switched to my other CMI8738 soundcard (the one with LX version of the chip) and it turned out that it is far less choppy sounding than the first one which I've tested yesterday - the one with MX version of the chip. I also tested SBEMU with /FIXTC1 command line switch, but in my …

I just found another problem related to Jemm on my test system. M$-DOS FORMAT and even NFORMAT produces garbage FAT on floppy drives. When I reverted back to HIMEM + EMM386 this problem has gone. I can confirm this issue to be generic. It happens if certain ISA DMA registers are trapped by "3rd- …

Thanks for the testing. It's also possible that the bug always exist even for -Os, but didn't expose after some code changes that affect it. - If you read from (or write with the same value to) a mem address twice, it's very likely that compiler will optimize the 2nd even using -Os, especially in a …
