Cart compatibility?

All official GB/GBC/GBA carts supported: ROM dumping, Reading and writing of all save types, EEPROM, SRAM, FRAM, Flash128k/Flash64k, GBA e-reader, Nintendo Power Cart, Gameboy Camera and more!

Bootleg Flashing: We regularly order new varieties of bootleg from Aliexpress/eBay/Taobao to check and add support where necessary. If you have an unsupported cart, head over to our discord and let us know. If you drop the link you used to purchase, we’ll make an order to ensure it’s added to the next firmware update.

How it works: Joey Jr needs no software or drivers. It works much like an external hard drive. You can drag your roms and save off, or on. You can play your cart directly in an emulator and saves will be automatically updated on the cart when you’re done. Easy! You can also use an application to access your cart’s files, like JoeyGUI or FlashGBX.

USB-C cable is required and not included.

*OSX support: Avoid using the drag and drop firmware as your MAC OS will write dozens of hidden files, confusing and potentially corrupting save files on your cart. Mac users please use FlashGBX software with the Joey Jr.

Firmware Updates: Note! NEVER UPDATE USING ANY FIRMWARE UNLESS IT IS FROM THIS PAGE.
