Retroflag GPi Case 2 Review: A Classic Handheld for Retro Gaming Enthusiasts

Overview

The Retroflag GPi Case 2 is a handheld gaming device that pays homage to the classic Game Boy design while packing modern hardware inside. It is essentially a shell and case that houses a Raspberry Pi Compute Module 4 (CM4), turning it into a portable retro gaming powerhouse. The device features a 3-inch IPS display with a 4:3 aspect ratio and 640x480 resolution, providing crisp visuals for classic games. It runs on open-source software and offers connectivity options like WiFi and Bluetooth.

  • GPU: Broadcom VideoCore VI (500 MHz)
  • RAM: 1/2/4/8 GB (depending on CM4 module)

Who It Is For

The GPi Case 2 is ideal for retro gaming enthusiasts who enjoy tinkering with Raspberry Pi projects. It is perfect for those who want a portable device to play classic games from systems like NES, SNES, Sega Genesis, and even some N64, PSP, and Dreamcast titles (though not all run at full speed). It also appeals to collectors who appreciate the nostalgic Game Boy aesthetic.

Buying Notes

Note that the GPi Case 2 is sold as a shell and requires a separate Raspberry Pi Compute Module 4 (CM4) to function. The base price of $80 does not include the CM4, and the optional dock adds $90. The device supports USB-C video output only through the dedicated dock. Performance varies depending on the CM4 model (RAM size) and cooling; some users may need to add heatsinks or fans for demanding games. The speaker is mono, and the build quality is plastic but sturdy.
