Seeing as the blitter (As I understand how it works) speeds up the Line-A type stuff, and seeing as GEM uses Line-A, wouldn't all GEM programs inherently be sped up? (Depending, of course, on how much of it was GEM and how much was custom drawing). > > > > 5._____ The new database from Timeworks is the only program currently on > > the market that uses the blitter. > False.

I'm not entirely sure about the exact direction of the original question, but: Those programs may be the only ones that EXPLICITLY use the blitter, but all programs that don't use all custom output drivers would use it if available, no? > -- > Ken Badertscher | Hey, umm, the stuff I said up there > Atari Software Test/Support | is, like, what _I_ think, okay? > {portal,ames,imagen}!atari!kbad | So, y'know, don't bug Atari about it.
