i've been on testing spree lately, so here's my whole list (i probably have some posted before, some may have changed cause i found some bugs)
Ikaruga --> no problems found, except that it's missing the black stuff at the side
StuntGP --> the screen where you buy parts for your car is totally messed up
Silentscope --> sniper not usable
Virtuastriker 2 --> music hangs and grass is missing in the intro movie, no other problems found
Sonic Adventure 2 --> sometimes the screen turns black for a sec, can't see the shadow of king boom boo (knuckles boss)
Crazytaxi 2 --> some traffic is transparent
Dead or Alive 2 -->sometimes the eyes glitch, so you only see a red spot
Capcom vs SNK 2 --> some 2d glitches with the characters
Sega smashpack vol.1--> games run slow and virtua cop2 freezes chanka when you choose it
Tony hawk's pro skater 2 --> major glitches on the normal version, almost no glitches on the old gfx version
Jet grind radio --> big graffiti not avaible, somehow it doesn't get the data to do it
Namco museum --> menu works great, games run too fast, overcloack the cpu to a high number
