Gameboy 4MB 128KB FRAM Flash Cart (Low power, Perfect for LSDJ)

This re-programmable Flash Cartridge is made for LSDJ users who want a low power cart with 128KB of FRAM which means no more batteries! Re-flashable with any flasher like GBxCart RW that supports the S29GL032.

This is the one of the lowest powered non-clone cart available on the market at ~10mA current consumption! Excellent for LSDJ (consumes a bit more power). Works with regular MBC5 games too and GB Studio MBC5 with saving if you wish to develop your own game.

Due to the cost/availability of the FRAM, we now have 2 sources of stock, international which may be limited to a few every month or so but is lower cost or via Digikey which costs more but we can order stock and receive it in a week.

This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. Games that require more than 4MB of ROM won’t work.

Check out the cart comparison image to see how each cart compares to each other and the clone carts. Check this list of Gameboy games to see the ROM/RAM size and MBC type your game will have.

Comes in a generic clear or grey Gameboy cartridge with our label if you like. Each unit is assembled in house and is tested on a Gameboy Advance. You can supply the ROM file for us to flash the cart if you like, it will be tested for 20-30 seconds to ensure it works.
