Install the last SDL.library for 68k (aminet surely) and the ixemul.library 48.0
- 48.2 (NOT THE V48.3) or the Bernd one - V61.1 last version) and try again with
some examples on aminet.

Some SDL 68k internal programs are compiled with newer SDL for 68k (not
available) and from the last SDL 68k to the never SDL 68k compiled on the
programs, the speed in the start is 2-3 frames on 68060 to now 10 frame.

640*480x16 argb SDL program in a window on a 800x600x16 argb screenmode.

Unfortunately, the same fullscreen open a 16 BIT screenmode and slow again (SDL
or P96 voodoo3 driver problem, I don't know).


also you could try last 68k ffplay and ffmpeg (aminet) with bernd ixemul for
your curiosity ;-)

Have contacted the author and answer me he don't have anymore voodoo3/mediator
stuff on his classic and now a cybervisionPPC (and he use also an AONE) that
mean he can't do other things for the rtg.library for P96 68k and for his
knowledge, the wrong colors with voodoo3/mediator driver can't came from the P96
side.... (But It's his point of view of course).
