* Increased support for SDK 4627 and all of it's "relatives"
* A minor increase in compatibility for commercial games.
* Started support for DirectSound3D (Highly unstable, not yet fully functional and can cause crashes). Must be enabled in the source prior to compiling.
* Support for many new texture formats.
* Fixed some issues with apps that use DirectMusic. Timing is still inaccurate!
* Added multiple new kernel functions.
* Fixed some SDK 4721 and 4928 "oddities" with certain APIs
* Possibly more things I can't remember.
