Fivefeet have already answered to the speed problem so i ll explain the next one...
The background (which should be pixellisated w/ ur monitor right?)
Is displayed as it should be on the real psx...
The TV and monitor aren t the same you know...well, if u can t play on a tv (I m lucky, i ve got a tv output but hum, sorry),
U ve got two choices:
Enable the bilinear filtering (if u are using pete s plugins) to extended, the second one in the pannel).
Or put scanlines on...(here s an hint; if u can manage to do it w/ ur comp, then increase resolution, say 1024x768 and enable scanlines...check a look at it
Bye
