Understandable, I got the canned response "We don't.share our IP" when I had asked creative for the documents, which was entirely expected. Turtle Beach was nice and simply said they didn't keep any of the Vortex2 documents after Aureal was shut down.

Turtle Beach replied to my request and stated they no longer have any backup copies of their Montego II board schematics or the documentation Aureal provided for the AU8830 at the time. I thought most large companies would have kept an archive somewhere...hmm, still waiting for Diamonds response.

CMSS-3D was "borrowed" from Q-sounds QMSS upmixing code, much like how the current SBX is actually a rebranded THX-TruStudio Pro. A bit of a jab but has Creative ever developed anything of their own "in house" and not recycled tech from prior third party acquisitions? Legitimate question here. It's …

Was an AU8830 datasheet containing the chips pinout diagram ever released? I might try contacting Diamond and the like to see if they wouldn't mind sharing the old MX300 schematics with me. [edit] shot diamond and turtle beach an email asking for them. Unrelated question, were there any Sensaura 3D …

Wouldn't an A3D wrapper/emulator make more sense? On a period correct machine not so much I guess. Many of these Windows 95 / 98 games are quite tricky to get going on modern PCs. Last year we got a bunch of Aureal videos uploaded of those games running under XP and it was hell getting them to go. …

Perhaps to a certain extent, but I would rather bring updated drivers to the AU8830 like the KX project did for the EMU10K1/2 cards. [edit] Actually a wrapper was already made but is horribly inaccurate. see http://www.worknd.ru/ Were there any other chips which had "dedicated" hardware HRTF cells …

I'm sure we'll discover if this is due to the hardware being the way it is, or simply a bad software implementation in which case it could be improved. Aureal didn't have much time to perfect it mind ya. [edit] The Vortex2 documentation states there should be some form of legacy hardware present: …

Hooked up my C64 to make sure it was still working after taking it apart to see which SID chip was in it, (6581 R4AR).

Update 02/18/2020: The new DOS TSR is still not running as solid as Aureals original driver, though there are some improvements over the original, it isn't stable enough. Protected mode games sometimes crash or refuse to detect the TSR emulation, I'm working these issues out currently, this requires …
