The framedrop is due to heavy debug output, game should work full speed.
UPDATE: More games.
I heard SEGA Tetris is pretty nice game but it sure doesn't look like much:
Samba de Amigo 2000 - yeah, I'm usually running JP BIOS dumped from my box so this is why most of you can't read the title :P
Still working on few other games, I'm seriously hoping this is the last batch for now or the next Makaron update will be in 2010...
