Apparently the recent Pac-Man & Galaga Dimensions game lacks the ability to erase saved data that's already on the cartridge which could be kind of a pain in the ass for players who are borrowing a friends copy, buying the game used, or who just want to start over. Well Namco has passed along this information they wanted to share with everyone: the saved data can be erased by holding down the A, B, X, Y, L and R buttons while booting up the game from the home-screen.

This is an old secret which we saw in some DS games before, and is of course the age old way to reset a stuck game so I'm surprised it took them this long either to figure it out or just to bother to tell everyone. Either way, you may now go about your business of erasing your saved data.
