Save Managers

This page lists devices that allow the backup and restoration of save files on original cartridges. Using these, certain runs become easier to run and to improve later, ie. segmented runs, ng+ runs. Be noted that not all games will be compatible with these devices.

The devices may perform other functions besides managing save files. Since there is a rule about console/game modification, while speedrunning (recording a video), players should not use these devices, or have them connected to the console/game cartridge. Their use should be limited to managing save files before starting and after finishing a segment.

The following list shows save managers for different consoles. Unless noted, they are able to make save backups from cart to PC and restore them from the PC to the cart. Next to the device name, a link to the main store for the device. Other stores such as regional distributors can be looked for on Google.
