The Retroflag GPi Case looks very similar to the original Game Boy, but it definitely doesn't play like one. The case features a 320px x 240px full-color display and requires a Raspberry Pi Zero. It's optimized for emulation software like RetroPie, so players can access a wide range of emulator cores.

The Retroflag GPI Case dimensions are 5.3" x 3.1" x 1.25" (135mm x 81mm x 32mm). It's really close to the original Game Boy, which measures at 5.69" x 3.2" x 0.97" (144mm x 81mm x 24mm).

In short, no. The Retroflag GPi requires a Raspberry Pi Zero or Zero W to work. It's up to you to install RetroPie and load games (referred to as ROMs) onto the Pi Zero. If you're not sure where to start, check out this list of free and legal ROMs then visit our guide on How to Add ROMs to the GPi.

To assemble the GPi, connect the Pi Zero to the IO conversion board, and screw the cartridge together. Put the cartridge in the GPi Case. Place 3 AA batteries in the back of the case. You will need a microSD card with a RetroPie image flashed to it in order to use the GPi. Visit our guide for detailed instructions on How to Set Up and Use the GPi Case.

ROMs can be transferred to the GPi over a network or with the MicroSD card connected to a computer via USB. To transfer ROMs over the network, you will need to enable SSH. Transferring via USB will require a MicroSD to USB adapter.

We have a detailed guide on How to Add ROMs to the GPi that breaks down each process for both Windows and Mac users.
