plural romsets

1. video gamesA group of related ROM images required to emulate a particular game.

   You are right re the romsets, MAME uses different sets for a lot of games, you can't intermix Neorage and MAME sets.

   I am looking for a rom dump of a Swedish or Finnish C64. They seem to have an alternate romset than the ones used elsewhere (probably because of the characters used in those countries).
