GBA 32MB, 4Kbit/64Kbit EEPROM Save, Flash Cart


This re-programmable Flash Cartridge allows you to play GBA games that support 4Kbit or 64Kbit EEPROM saves. For a full list of games that should work, please check out the listing here and search for “gba_eeprom_4k” or “gba_eeprom_64k” or check the list of games we have tested below. Any game without saves will work. You will need GBxCart RW to re-write this flash cart. Designed and made in Australia.

Need to flash a game on this cart? Make sure to grab our GBxCart Flasher.

Out of stock due to the chip shortage, there is no ETA but we have been waiting since June 2021. Sign up for a notification when you make a selection in the options. Once back in stock, we will be doing small batches, going oldest to newest, sending users email notifications with special links until all notifications are cleared.

Depending on the size of your game, you will have to change the switch from 8MB/16MB to 32MB, this is due to the way the EEPROM is addressed. If you purchase both the 4Kbit and 64Kbit EEPROMs on the same cart, you can use the other switch to change between them for different games. Before flashing a 16MB or higher size ROM, please change the switch to be 32MB. Please note that the last 256 bytes of a file won’t be programmed as this is where the EEPROM address is.

Another flash cart option is the GBA 32MB, 256Kbit FRAM save cart. By using GBATA, you can patch games using the 4Kbit/64Kbit EEPROM save type to save to SRAM/FRAM instead.

This cart should work on every system that supports GBA carts – GBA, GBA SP, GB Micro, DS, DS Lite and the Game Boy Player. This cart uses 5-10mA more compared to a regular cart. If you would like us to test a game, check the “Game saves tested” list.

Comes in a generic GBA cartridge. The board won’t fit in a genuine cartridge. Each unit is assembled in house and is tested on a Gameboy Advance.

The PCB finish is ENIG.

When you place an order, if you would like the flash cart to be programmed with a ROM, you need to supply it to us via email (you can reply to your order notification). It will be tested for 20-30 seconds on a Gameboy Advance to ensure it works, if it doesn’t work, we’ll contact you. If you don’t specify a ROM, it will be loaded with the “Graveblood Pre Pre Pre Alpha” Game Demo.
