GBA Backup Tool

TypeSystem Tools

GBA Backup Tool is a tool that allows us to extract the rom and the save of original GBA cartridge. With this version, user can remove game saves that are formatted EEPROM.


GBA_Backup_Tool.nds is DLDI compatible, so patch it according to the research tool to be used.

Modify GBA_Backup_Tool.ini with a text editor according to the usage environment.

Copy GBA_Backup_Tool.nds and GBA_Backup_Tool.ini to the root of SD. If GBA_Backup_Tool.ini does not exist, the default operation will be used (usually it is okay to omit it).

User guide

Note: Please use at your own risk as problems such as corruption of SAVE data in GBA ROM may occur.

Start GBA_Backup_Tool.

Use L and R to switch between Save Backup, Save Restore, and Rom Backup.

Save Backup

A - Updates the contents of the specified SAV file as a backup with the contents of SAVE in ROM.

B - Creates a new SAV file and backs up the contents of SAVE in ROM. The name of the automatically created SAV file is GameTitle_GamecodeRomVer.sav (.sv0 to sv5). Overwrite the file.

Save Restore

A - Restores (writes) the contents of the specified SAV file to SAVE in ROM.

B - Initializes the ROM SAVE area with 0xFF.

Rom Backup

A - Updates the contents of the specified GBA file as a backup with the dumped contents of the ROM.

B - Creates a new GBA file and backs up the dumped contents of the ROM. The name of the automatically created NDS file is GameTitle_GamecodeRomVer.gba. If you already have a file with the same name, it will be overwritten automatically.

Note from developer:

If the ROM SAVE type cannot be determined, unknown will be displayed.

The judgment of the ROM size of GBA ROM is sloppy. In case of over-dump, you can use other tools such as GBATA to trim/make it to the correct size.



X - Replace the Slot-2 GBA ROM cartridge

Start - Exit program and turns off the power of NDS

A/B - Operations

L/R - Switch mode
