At least works with Pac-man & Galaga 3DS
The drama surrounding the inability to wipe save game data from the Nintendo 3DS versions of Pac-Man and Galaga Dimensions has apparently taken an interesting turn, with the revelation that you can actually wipe the save data from the cartridge.
Initial reports suggested that it was impossible to erase the save game data off the Pac-Man and Galaga Dimensions cartridges, according to a number of sources. While we don’t know if it will work to wipe game save data from other cartridges, it does seem to work fine with these two titles.
Apparently, all you need to do once the game boots up is to input “ABXYLR” and the save game data will be wiped from the cartridge. It is currently unknown if this code will work with other cartridges that were said to suffer from this issue. We suspect that we will hear more about this once more folks have a chance to test and figure out what the deal is.
