As for Smash 64 on VC for Wii, the data cannot be copied and/or transferred and played on another new Wii because VC games are specific to each system. Similarly, in the Wii U version of Smash 4, the game data cannot be copied and/or transferred from one Wii U to another (nor to an SD card). In Brawl, the game data can not be copied and/or transferred from one Wii to another (nor to an SD Card).

In Smash 64, the game automatically saves through the Nintendo 64 game cartridge on the N64. However, while that is possible in Melee, this is not possible in other installments (such as Smash 64 -either version including N64 and on VC for Wii-, Brawl, or Smash 4). If the player does erase all data, a copy of the game data would be wise to create on a separate memory card.

When 'Erase All' is selected and the data (all data) is erased, there is no way to recover it. Brawl- the option to erase only one category of data is available (including an 'Erase All' function). In the first three installments of the series - Super Smash Bros., Super Smash Bros. It allows the player to erase (and lose) any specific data in the game, such as high scores, trophies, and more. Erase Data is an option appearing in all four installments of the Super Smash Bros.
