_fast?

[seamoon]

Some emulators, mame and pocketsnes comes to mind on top of my head, have two executables, one with the suffix _fast added. What's the difference between the standard gpe-file and the one with _fast added? I have not noticed any difference.

I would assume some special optimizations, but not without side affects. A good example is Ninja Princess in Mame. Normal version works fine, while fast version has an odd effect with the game's enemies. They are all shadowed out on the fast version for me. I generally do NOT use the fast versions personally, as I prefer compatibility to speed.
