Freeplay CM3 / Zero Review: A DIY Retro Handheld with Raspberry Pi Power

Freeplay CM3 / Zero Review: A DIY Retro Handheld with Raspberry Pi Power

Overview

The Freeplay CM3 and Zero are DIY handheld gaming consoles created by Freeplaytech. They are designed for enthusiasts who want to build their own retro gaming device using Raspberry Pi modules. The CM3 version is powered by the Raspberry Pi Compute Module 3 (BCM2837B0) with a quad-core Cortex-A53 CPU at 1.4 GHz and 1 GB DDR2 RAM, while the Zero version uses the Raspberry Pi Zero (ARM1176JZF-S at 1.0 GHz) with 512 MB DDR RAM. Both feature a 3.2-inch TFT display with 320x240 resolution (4:3 aspect ratio), a 2000 mAh battery, and a plastic yellow shell reminiscent of the Game Boy Advance. The CM3 variant includes Bluetooth, WiFi, USB, and Mini HDMI output, whereas the Zero lacks these connectivity options. Storage is via external MicroSD card. The devices run open-source operating systems and can emulate games up to N64 and Nintendo DS.

Who It Is For

The Freeplay CM3 and Zero are perfect for DIY enthusiasts and retro gaming fans who enjoy assembling and customizing their own handheld console. They are not for casual users seeking a plug-and-play experience; instead, they require some technical knowledge to set up the software and hardware. The CM3 variant is better suited for those who want built-in connectivity and more power for emulating higher-end systems, while the Zero is a budget-friendly option for simpler retro games.

Buying Notes

As of 2017, the Freeplay CM3 and Zero were available as kits or pre-assembled units from Freeplaytech. Prices were around $120 for the Zero version and $150-$200 for the CM3 version. However, availability may vary, and these devices are no longer in active production. Potential buyers should check second-hand markets or community forums. Note that the Zero version lacks WiFi, Bluetooth, and USB, making it less versatile. Also, the 320x240 display is low resolution by modern standards, but it suits the retro aesthetic. The battery life is decent for a device of this size, but heavy emulation may drain it faster.
