Now work:
BioHazard Battle
Mega Turrican
Dune
MicroMachines Military
Mr Nutz
Ristar now looks completely correct
Smurfs 1-2
Sonic Spinball
SplatterHouse 2
Sunset Riders
Super Skidmarks: messed menus, but working ingane (green shadow, and low fps)
Talmit's Adventure: works, but the clouds are still green
TMNT Tournament Fighters
Tiny Toon Adventures - ACME All Stars (sometimes, not always, hangs at 166Mhz)
Tiny Toons - Buster's Hidden Treasure
MicroMachines: correct menus, totally invisible the game
Pebble Beach Golf Links: the game restarts when you select to start a match
MicroMachines 96 resets the GP32
Radical Rex resets the GP32
Scrabble resets the GP32
Street Fighter 2 Special Champion Edition: SEGA logo and then... black, after a few seconds it resets the GP32
Super Hydlide does not save the created character and then hangs
Zool resets the GP32
Looks like this version, at 166Mhz sometimes hangs my GP32, while the old one never did it:
I tried a lot of apps at 166Mhz, and my GP32 never crashed/hanged.
If I set 164Mhz (!) it works: I have verified this playing ThunderForce 4 and other games
