[Odyssey] This isn't necessarily an error, but games 1-6...

Games 1 through 6 are not listed seperately. Maybe this is done on purpose, I'm not sure, but, this is a little problem for someone like me, as I only own cartridge 1 for it.

Yes, it's a problem I've thought about with an entry in the C64 database too (30 multicarts all from the same manufacturer in Poland). Will be adding them all in separately in the near future instead.
