    Racer Ball, Rommel 3D, Android Attack).

    Korhonen's code.
    * Refactored code to something a little more logical.
    * MacOS X 'Carbon' UI contributed by Stuart Teasdale.
    * Use C99 types instead of SDL ones except in SDL-based drivers.
    * Wrote faster GP32-specific VDG routines.

    Version 0.9, Sat May 15 2004
