A3D wrappers gave some promising yet preliminary results. Under the game Motorhead, which supports both A3D 1.2 and A3D 2.0, the "repackaged" Creative a3dx5 wrapper allowed the game to utilise A3D 1.2. However A3D ALchemy managed to pull of A3D 2.0 of the game. A3D-Live supported both A3D 1.2 and 2.0, but the latter had reduced engine noise.

EAX has been supported in most games (didn't test FMOD ones for my own ease) except a few need some patched files. I didn't verify the "authenticity" of the special effects, I just made sure if the positional sound is present or not...

Trying to find the original creative a3dx5 wrapper. There is repackaged one in PCGW but I am looking for the one as in an official site (probably in web archive).

Can't find any source on QSound A3D

Here's what I've got so far: https://kutt.it/BinauralWrappers ( https://airtable.com/shrNC8TQOVrknviGs )
I'm also looking for official source/download URLs so let me know if you have changes/suggestions for my list, or the database for that matter: Binaural Audio Database (3D audio/surround sound/EAX emulation guides, demos, etc.)
