* Region switches for Street Fighter Zero CPS Changer and Pnickies
     * YM2151 logging. Logs to Callus style CYM file. Works better if enabled
       from the start of the game (before pressing Enter, after loading)
     * Changed the balance so OKI is louder compared to YM2151 (clearly, better CPS1
       sound :P)
     * Cleaned the startup code. May fix some crashing issues...
     * New windowed mode features :
         - Tab shows/hides the menu bar
         - Ctrl+1, Ctrl+2, Ctrl+3 resize the window to 100%, 200%, 300%
     * Added a DirectX check. DirectX is needed for Kawaks to run. If you don't have
       DirectX, Kawaks will display an error and quit cleanly. (you can't imagine
       all the "bug reports" I get from people who don't have DX installed...)
     * Alien vs. Predator (Euro 940520)
     * Street Fighter Zero 2 Alpha (Japan 960805)
