I tried running some emulators on a P166 w/ 1 mb of gf card! and here's the results
Good Speed-
Nesticle - NES emu, no reason not to.
Genecist - GEN emu, no reason not to.
ZSNES DOS Ver. - SNES, works pretty well. up to 20 fps
Raine - Multi Arcade - Works miraculously well! 20 fps!
Bad Speed -
SNES9x - bad frame rate
MAME - really bad frame rate!
anymore that works good on slow comps???
