Tecmo bowl: major player switched, same title screen, same base label code, same game
Tecmo NBA: most important player removed, same title screen, different label code, same game
Punch Out: boss sprite swapped, slightly different title screen, different label code, different game?
Theres a bunch of same game - different games out there that make no sense.
contra and probotector? SAME GAME!
mario 2 & doki doki panic? DIFFERENT!
Snowboard challenge & Heavy shreddin? same game!
Mario Bros. & Mario Bros Classic series? COMPLETELY DIFFERENT GAMES!!!
Bubble Bath Babes & Mermaids of Atlantis? Different
Impossible Mission AVE & Impossible Mission SEI? Different
Myriad & Caltrain? Different!
Ninja Turtles & Hero Turtles? Same
Ninja Gaiden & Shadow Warriors? Same.
Theres zero consistency in the grouping conventions of same-game. Can’t go by seal of quality either because uh-oh, anticipation, Mario 2, and various others have no-seal variants. Can’t go by “left Nintendo’s factory” because Konami, and Acclaim made their own carts...can’t go by “Nintendo authorized it” because then you need to include NWC gold and maybe even grey.
Whole list is messed up, but it works well enough.
