I think those need more investigations, like incompatible games. Not sure I can fix it but I'll try. Happy to report further success on several fronts with the latest (22-Feb) binary. 1. 16-bit audio now works! (mostly, somewhat finicky), and the emulated card detects as SB16 DSP v. 4.0 and I …

- New Options added: /T, set the sound blaster type, same meaning as the values in BLASTER variable. default value is /T5 (SB Pro), you may change it to 3 or 1 if encountering some emulation problems. /T6 (SB16) will add extra T6 H5 to BLASTER env var. /O[1/2], for Intel HDA only: 0 - output to …

There seems to be some retrogression with your latest (20-Feb) binary which sets the BLASTER variable without one needing to manually set it. With this version, I've run into incompatibilities with many real mode programs which "expect" only an 8-bit DMA and / or an SB 1.0 or Pro card. So, I've …

So am I right in thinking this may get DOS sound working on an nforce2 system? Can't see why not. The onboard audio chipset is what matters, This SBEMU project is using the libau PCI code database, it seems. Any system that still has legacy 16-bit vBIOS code and legacy boot mode via CSM will …

I don't get it. If JEMMEX finds an XMS driver, it refuses to load. The newest, pre-release version of JEMMEX is required for SBEMU to work as QPIEMU.DLL is a JEMM386 module. How can you combine JEMMEX with an external XMS server (I use XMGR + UMBPCI, bythe way). Also, I did not know there is an / …

Yeah. I fixed some bugs in MPXPlay too. It did have no sound in Virtualbox with HDA, it uses PIO for immediate commands while Virtualbox only support MMIO, I read the HDA spec and found the PIO are optional only. the ICH driver also have tiny bugs and I fixed them. lol Thank you! You are a genius. …

Most likely this is not an SBEMU specific problem but a broader problem related to all DOS4GW titles running under v86 mode: https://www.bttr-software.de/forum/forum_entry.php?id=15770 I figured as much. And seems v86 mode will trigger the same behavior (unable to set write-combining caching mode …

Intel IHD audio = Intel High defection audio = Intel HDA? I thought they were the same thing. :D Yes, I believe they are. There was some confusion because MPXplay refers to Intel High Definition Audio as IHD, while others just refer to it as HDA (High Definition Audio). So, there's no problem now, …

I've no idea what's happing lol, I didn't use EMS at all, but only XMS for sound card driver's buffers. It might need more investigation. I see. May I disable EMS completely when loading JEMM, and still use SBEMU? Mostly, I prefer XMS over EMS unless a game specifically requires Expanded memory ( …

Try doom with dos32a then. Are you sure the ess solo-1 is not using any resident software to emulate SB? I have such card and can test it too after a day or two.

crazii, I can report success with SBEMU! It is wonderful. I have a few questions, and although it works, it seems very finicky, giving lots of exceptions, divide by zero, and / or system freezes. But, most importantly it works on the three new core i5 and i7 systems I've tested it on so far: two …

This seems like a dream project. Most of my modern systems (laptops) have Intel IHD / HDA audio, but I have a couple of desktops with AC'97 codec and I'll try them. Should I stick to DOS4GW (most of which I've stubbed over to DOS/32a, which claims to be 100% compatible and improve upon the original …

Edit: It appears that the version 1.0 hasn't been tested on real hardware as there are sound problems like in DOSBox-X. Wish there was an option to disable sound entirely. Who needs 6+ MB of .wavs cluttering up the game? They should be optional, and the game should run silently, even if they've …
