Would the Action Replay Max let you install the memcard boot thing from a UMCDR or does it just let you play media files and Megadrive/Genesis Roms under P-Gen?
I don't have a working PS2 at the mo but I installed the memcard boot system ages ago anyway with an old Action Replay/swop trick, butif theMax lets you do what I thibnk it might beable to do you wouldn't need a swop trick, it would also depend if the install method can be run from a UMCDR aswell
UMCDR being an odd format of CD-R that can run under the memcard thing without any tricks, and is also what the Max version of the Action Replay uses
