... ques and even split screen effects can be applied. The Dual Playfield screen mode works on 4, 8, and 16 bits color depths. The following text is from #gp32dev irc channel (that I wrote in a frustration and rage at 02:38am): [2:38] spiv|ZzZz well doods.. to enable pseudo usefull for nothind mr.spiv (tm) two layer screen mode with annoying transparency just pump the frame refresh rate over 100Hz and flip two framebuffers every 0.01sec.. to get the other layer to appear to "foregroung" layer set intensity bit to 1 for those colors it uses.. by copying palette on every frame buffer flip you get easily 32 colors 4bits screen mode [2:39] spiv|ZzZz worx on ...

I haven't benchmarked any of this, so if anybody out there feels he/she wants to verify this data then please do so, you'd make me very happy. Thanks to exoticorn for teaching me all about ARM code and mr_spiv, darkfader, mp and others for helping me out here and there. I hope this doc will help people write fast code for the GP32. Maybe a decent megadrive/genesis emu? and now for the goodies: 1) cycle timings Most instru ...
