Well out of a full set that's not too many. Either your set was slightly newer than the one FBL uses, or slightly older. It can be hard tracking down slightly older individual roms after MAME has been updated, coz most romsites only keep the newest files up. Maybe someone with a fully green FBL romset will PM you and point you in the right direction. That won't be me though I'm affraid, I don't actually have a MAME set at the moment. I need to grab a 0.137 super set torrent at some point. i used mame .135 when i did this... no biggie on getting these now though. i haven't played fbl in over a month and a half. no offense nes... gotta life, wife, 2yr old son.
