Nintendo 3DS game Pac-Man & Galaga Dimensions does prevent users from deleting their save data, Namco Bandai has confirmed.
"There is no way to erase the save from within the game itself without misusing the hardware, causing corruption," the Japanese publisher told Shacknews.
Namco Bandai failed to explain why it took the decision, however.
It did, though, stress that the game's save system, which it calls "save schemtata", is not as black and white as Resident Evil: The Mercenaries 3D's, for example, because it contains multiple games on one cartridge.
Gamers will be able to save high scores and share them with others online, the publisher stated, but if the same cart is used in a second 3DS, "scores may be double posted online."
"It takes a very long time to get high scores on all the games to fill up the rankings as each game is a stand-alone title," the publisher explained.
Completing just one of the included games would take an average person eight to ten hours, Namco Bandai said.
"With 6 games, that's 60+ hours to fill up everything with good high scores."
Capcom pointed to The Mercenaries' high-score, arcade gameplay when explaining its decision, dismissing the suggestion it was an attempt to combat used game sales.
