Gameboy LinkNLoad32 USB Flash Cart (4MB, 128KB FRAM) [Coming soon]


The Gameboy LinkNLoad32 is a Flash Cartridge which features a Micro-USB port so you can re-program it anywhere you go as long as you have a USB cable and a computer. You can also backup and restore your saves too. Simply use the GBxCart GUI or Console interface programs that you might already be familiar with which works with Windows, Linux and Mac. Check the video below of the prototype cart.

Expected by the 10th of July 2020

This is perfect for LSDJ users who want a low power cart with 128KB of FRAM which means no more batteries! 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 this list of Gameboy games to see the ROM/RAM size and MBC type your game will have.

Comes in a generic clear Gameboy cartridge with a small cut out (originally for an SD cart slot) for the Micro-USB connector. 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.

SKU: N/A Category:


ROM: 4MB Flash (S29GL032)
FRAM: 128KB (FM28V100) – No battery needed!
MBC: MBC5 emulated with a Altera CPLD
USB port: Micro-USB

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.

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 LSDJ Stable 7.0.2.
