ROMs working in actual emus..

[solidous]

I tested just with the snes emu until now and:

SMAS = fine 266mhz 3fr.s.
rocn roll racing = slow 266mhz 3 fr.s.
zelda = fine 266mhz 5fr.s.
mario kart = slow 266mhz 3fr.s.
yoshi sland = dont work, crash the emulator.

I will update it soon.

All games tested at 333mhz and 3 fr. s with sound ON.
Tactics Ogre - Crashed after selecting 'New Game'
Ys IV - Plays well.
Ys V - A bit slow but playable, I'd suggest waiting for a newer emu before trying the 'Expert' version...
Castlevania IV - Very slow
Chrono Trigger - A bit slow but not too bad.

i've found that many games need to be started with the original resolution before stretching, otherwise it's all screwed up

Ill add my part:

Super punch out = 333mhz plays well
F-zero = 333 mhz, okay but somewhat jerky with sound

Generally hi res games slow it down and also those with several enemies or interactive enviroments.
