    I need help with this MPH code using the R4's Action Replay. I want to unlock every single playable arena for MPH but the code: "All Planets Open" (Cheat Code- 020e8c64 ffffffff) doesn't work. Not sure if that's the right code to unlock the arenas. =P Can anyone please help me with this? What code should I use? Should I change the CHEAT.DAT file? [​IMG]
