New SNES Ken Griffey Jr.'s Winning Run codes unlock Nintendo and N64 teams instantly

New codes for SNES Ken Griffey Jr.'s Winning Run let players immediately use hidden teams in two-player or exhibition matches without save data. The codes (Tampa Bay Devil Rays: X X X Select; Arizona Diamondbacks: A A A Select; Nintendo: B B B Select; Nintendo 64: Y Y Y Select) require starting a 2P or exhibition game and holding L or R on the pre-match screen while entering the code. Successfully entered, the game plays a cue and switches to the hidden team. The Nintendo NOA roster and the entire N64 roster reflect their era (NOA president Minoru Arakawa and Rareware developers, respectively).
