Hardware M3 Update

[Bridgy84]

Is v35 the absolute newest update for the M3 Perfect? I'm having some issues here because I'm kinda new to the slot 2 stuff.

-Edit: Also, I keep getting a warning every time I load up after playing a game that says, "Warning! GBA GAME SAVE in card but CANNOT find AUTOSAVE backup file. Backup fail!" What's the solution to this?

Thanks!
