SDL_BlitSurface is the central hub in SDL to move pixel data around. It also covers implicit conversion betweeen different pixel formats. That's why I wrote a number of routines for typical...

If desired, the AMMX routines can be disabled entirely by disabling the Apollo_EnableAMMX() call. But in any case, the mentioned call does check whether the code is running...
