Retroflag GPi Case Review: A Classic Game Boy-Inspired Retro Handheld

Retroflag GPi Case Review: A Classic Game Boy-Inspired Retro Handheld

Overview

The Retroflag GPi Case is a handheld gaming shell designed to house a Raspberry Pi Zero (or Zero W). It mimics the classic Game Boy DMG-01 design, complete with a D-pad, A/B/X/Y buttons, and a 2.8-inch IPS display. Powered by the Broadcom BCM2835 processor (1 GHz single-core ARM1176JZF-S CPU and VideoCore IV GPU), it runs RetroPie, a popular emulation OS. The device uses 3 AA batteries for power and connects via Bluetooth and WiFi.

Who It Is For

The GPi Case is ideal for retro gaming enthusiasts who enjoy DIY projects. It requires a Raspberry Pi Zero board (not included) and some setup. It's perfect for playing 2D games from systems like SNES (most run at 60 FPS) and 2D PS1 games (most run well, though not always at full speed). 3D games may struggle. It's not for those seeking a plug-and-play experience or high-end emulation.

Buying Notes

Prices range from $70 to $100, but you'll need to supply a Raspberry Pi Zero and a MicroSD card. The case is well-built and nostalgic, but battery life depends on AA quality. Consider the form factor: vertical grip similar to the original Game Boy. Check for compatibility with your Pi model (Zero or Zero W).
