Rumour has it that as Satoru Iwata gave the full specs of the Gamecubes SuperMarioVisionAtron (SMVA) cpu to the developers (The first time anyone outside of nintendo has seen them) almost every game is working. The only problem is that most of them need an xbox fishing controller
(as seen here) or the Steel battallion controller
(Seen here). The only problem with that is the controllers are quite rare, so you crazy gamecube freaks better hit up ebay or your local gamehole asap.
