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).
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.
Be sure to check out our GPi setup video as well:
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.
The GPi batteries tend to last for several hours. Factors like screen brightness, processor demand, volume, and even battery type can impact the longevity of the battery life.
In our experience, the GPi can typically last for 3-5 hours on fully charged AA batteries.
No, the Retroflag GPi Case does not come with a Raspberry Pi Zero. You must separately purchase a Raspberry Pi Zero or Raspberry Pi Zero W to use with the GPi Case.
The Retroflag GPi Case requires a Raspberry Pi Zero or a Raspberry Pi Zero W to operate. The case does not come with a Raspberry Pi—be sure to order one when purchasing your case.
I recommend the Raspberry Pi Zero W, which comes with wireless capability. This will make configuring the GPi far easier.
The Retroflag GPi Case can use WiFi if it was assembled with a Raspberry Pi Zero W. WiFi can be used for over the network ROM transfers, OS updates, software installs, and more. If you're using a Raspberry Pi Zero, these features won't be available. Updates will need to be flashed to the GPi via USB.
The GPi relies on a Raspberry Pi Zero for processing power. The $5 computer may be small, but it packs an impressive punch. It easily emulates GameBoy and NES titles. In most cases, you can emulate Super Nintendo ROMs—but you may need to use frame skipping to improve performance.
