Joey Junior JR V2++ plug & play writer & flasher for Gameboy, Color, Advance Cart - USB C game cartridge backup adapter GB GBA GBC with 3D printed enclosure | Benn Venn

Perfect

Is literally just plug and play

This works as it’s supposed to, no hassle or issue whatsoever. Plug it into a laptop with a game, and it recognises it like it’s a USB drive. It will contain the game’s Rom file and save data. It’s that straightforward. I tested it by playing the Rom on an Everdrive, with the save data, and it recognised both no problem. I’m in the process of replacing the batteries in loads of my Game Boy games, so this will be invaluable. It also contains RTC data for the Pokemon games which have a real-time clock. There are more advanced functions but I haven’t tried them yet. I also tested this with a GB Camera plugged in, and plugged the Joey Jr directly into my iPhone 15 Pro, which has a USB-C port. The Joey Jr came up as a drive in the Files App and you could view all the photos from it. I’ll probably never use that but I found it neat nonetheless! All in all I cannot recommend this enough if you have lots of GB/GBC/GBA carts.

Was exactly as expected

Fast delivery and exactly the device I was looking for now I can backup my Tetris saves and move it over to my emulator.
