GB 64MB Mighty Flash Cart (Coming soon)

  • Instant game loads
  • 64MByte storage space
  • 32KByte FRAM
  • 8 Save slots (optional)
  • Easy to use drag & drop GUI

This re-programmable Flash Cartridge gives you 64MB to load your ROMs, you can enable the save game manager to allow you to save/restore to 8 slots and you can simply drag and drop your ROMs with our GUI to generate the ROM file to flash.

Allows you to play most Gameboy/Gameboy Colour games including Pokemon (no RTC support), Zelda, Wario Land, LSDJ (only 1 save), etc.

At this time, this flash cart can only be used with our GBxCart RW flasher if you wish to write more than 8MB to it. The MBC5 mapper is the default, use our Multi-game loader to play MBC1/3 games.

This cart works on every Gameboy system – GB, GBP, GBC, GBA, GBA SP and the Game Boy Player but due to the high current draw on v1.0, it isn’t recommended for the Gameboy Pocket or GBA SP. Games that require more than 32KB of RAM won’t work.

Check out the cart comparison image to see how each cart compares to each other and the clone carts.

Comes in a generic clear or grey Gameboy cartridge with our label. 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.

We usually ship within 2-3 business days and the usual delivery time is 2 to 4 weeks. This product can be back ordered, you’ll be provided with an ETA when more stock is expected, usually it’s 2-3 weeks.

This product is currently out of stock and unavailable.

SKU: N/A Category:


ROM: 64MB Flash (S29GL512)
FRAM: 32KB (Data retention of 20-50 years)
MBC: MBC5 by default. Use our Multi-game loader to allow for MBC1/3 games.

The PCB finish is ENIG, Gold fingers (on the edge connector) with a 45 degree bevel to give the maximum life for insertion/removal of the cartridge.

This flash cart will draw 120-140mA more current compared to a regular cartridge due to the CPLD so you will see a decrease in battery life of at least half.

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 LSDJ Demo.

How to use

Flash Cart

If you use our Multi-game loader, you will be presented with a list of games, use the up and down arrow to scroll through the list and press A to launch the game – the Gameboy will restart and the game will be loaded.

Save Manager

If you enabled save slots, you will have access 8 save slots by pressing the Start button at the loader screen.

You can give the save slot a name by pressing A when selecting a slot number and then using the up/down arrow keys to cycle through characters. Press B to exit if you give it a short name. The save name will only be saved when you save the RAM to the slot.

To save the RAM to the slot, select the “Sv” option and press A. It will take about 30 seconds to save.

To load the slot into the RAM, select the “Ld” option and press A. It will take about 30 seconds to load.
