First thanks for Romcenter, its great.
I have let Romcenter go through my database, now I have green and red Roms.
The problem I try to solfe is how to delete/filter all green roms that contain games that mame states don´t work at the second splash screen in mame (First splash screen: Playing roms you dont own is illegal, Second: This game doesnt work, Rom dump incomplete, etc.., Third: CPU etc..) ? I have a lot of Roms and most of them dont work, i.e. almost all roms >100mb or all roms using powerpc >100mhz dont seem to work yet, also virtua cop etc..
