OK, I've gotten a few games to work on the E740, but am not really pleased with the results:
Tank Force (a 1990 game that used 3 6809 processors, and a sound processor) runs way too slow on the E740 to be usable. Only about 1 or 2fps w/o sound!
Galaxians (a 1979 game that used 1 Z80 processor @3Mhz) updates pretty slowly. About 14fps(70% of what it should be) w/o sound, and a very jumpy 6-13fps w/sound
Even Space Invaders (a 1978 game that used an 8080 @2Mhz) isn't that good. It runs at about 16fps w/o sound(80% of what it should be), which is "almost" good enough, but not quite.
I was hoping for more... is it possible that these games' performance could be increased on the E740, by creating specific drivers for the E740... or am I doing something wrong?
