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.

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.
