I thought Pac-Man Collection released by Mode 7 seemed a bit large so cut it down to 32 Megabits (4 Megabytes) and it works fine.. oversized release; no biggie. Undoubtedly some lamer (or Rapid Fire) will re-pack and re-release it in a 32 Megabit size.
FYI for those that want to put it on a Flash Advance card and don't want to waste the whole card.
