Gameboy 4MB 32KB/128KB SRAM Flash Cart (Coming soon)

This re-programmable Flash Cartridge allows you to play most Gameboy/Gameboy Colour games including Pokemon (no RTC support), Zelda, Wario Land, LSDJ, etc and allows you to re-flash it with any flash cart programmer like GBxCart RW that supports the ES29LV320. It also allows for some MBC1/3 games (you need to use our loader) that don’t work properly on clone carts such as Super Mario Land 2, Donkey Kong Land 3, Megaman 5 to name a few.

This is the one of the lowest powered non-clone cart available on the market at ~10mA current consumption! Excellent for LSDJ (make sure you select the 128KB option).

This cart works on the GBC, GBA, GBA SP and the Game Boy Player. Games that require more than 32KB of RAM won’t work. Doesn’t work on the original Gameboy or the Gameboy Pocket.

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. 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.
