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

(1 customer review)


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. Designed and made in Australia.

Out of stock due to the chip shortage. Parts supplier ETA is around April 2022. Sign up for a notification when you make a selection in the options.

This is the one of the lowest powered 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.

We’ve now added a rumble PCB option so you can play Pokemon Pinball, Perfect Dark, Star Wars Episode I – Racer, etc. If you load LSDJ on the rumble PCB, the rumble motor may be activated very briefly while loading/saving songs. The cart will also rumble when re-flashing it.

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 this list of Gameboy games to see the ROM/RAM size and MBC type your game will have.

Comes in a generic 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.

    Works exactly as I hoped it would. I test both Pokemon Yellow and Silver versions with Pokemon Stadium 2. Yellow also worked with Pokemon Stadium. I used original dumps of both games and flashed each one to test so no rom hacks required.
