Save data
In, , and , after the player stops playing an NES/Famicom game, the game saves the high score (or saved game progress in the case of ) to the Nintendo GameCube Memory Card, taking up one Block in a separate save file from the town data.

NES/Famicom data cannot be saved if the Memory Card containing the town's data is not inserted into the GameCube.

Advance Play
In and, the player can choose the "Advance Play" option when interacting with an NES game to download the game to a Game Boy Advance that is connected to the Nintendo GameCube. The game can then be played on the GBA until it is turned off, even if it is disconnected from the GameCube. The GBA can be reconnected to the GameCube to save the NES data. When playing on the GBA, the graphics are compressed to fit within the GBA's much lower vertical resolution compared to the NES. Multiplayer modes are not available during Advance Play, and ', The Legend of Zelda, ', and  cannot be played via Advance Play as they are too large to be stored in the Game Boy Advance's RAM.

Unused functionality of the NES item
In 2018 it was discovered that when the empty item is interacted with, the game scans the Memory Card (Controller Pak in ) for NES/Famicom ROM data. NES/Famicom ROMs, including those not already in the game, can be patched and placed on a Memory Card, where they can be loaded and played by interacting with the item. Interacting with the item with multiple NES/Famicom ROMs on the Memory Card displays unique text that is normally unused: "Should I play my NES software?", followed by a list of games.

In, if the Controller Pak has NES/Famicom ROM data on it, selecting the "てがみをほぜんしたい" ("Save a letter") option at the post office brings up a normally unused menu titled "コントローラパックのきろくをけします" ("Erase Controller Pack Records"), where the NES game data can be viewed and deleted. In, the Chinese title text for the menu is corrupted and the original Japanese text is left untranslated for all other text in the menu.
