SJGAM M20 is a gaming handheld launched in 2023. Powered by RK3566 (4-core, 1.8 GHz), 4 GB RAM. Features a 7" display (1024x600). 4000 mAh battery. Runs EmuELEC (Linux).
At its heart sits the RK3566 processor, with four Cortex-A55 cores running at 1.8 GHz, backed by 4 GB of RAM. This is an entry-level configuration focused on emulating classic systems and retro libraries, where efficiency matters more than raw power. The 4 GB of RAM provides comfortable headroom for the interface and emulators.
The 7-inch display is one of the model's highlights, offering a generous viewing area for a handheld. The 1024x600 resolution is modest for this size, but it suits retro games well, since they were originally designed for much lower resolutions anyway.
The horizontal form factor provides a classic control layout that many players appreciate for retro gaming sessions. The large screen makes the M20 better suited to playing at home or while travelling rather than slipping into a pocket.
The battery has a capacity of 4000 mAh, which has to power a 7-inch screen, so real-world runtime will depend on brightness and the systems being emulated.
On the software side, the M20 runs EmuELEC, a Linux-based distribution dedicated to emulation that brings emulators together under a unified interface. Modding is permitted, so users can tweak and customise the system to their liking, a key advantage for the retro gaming enthusiast community.
Ideal for: players looking for a horizontal retro handheld with a large screen, users who prefer an open Linux system like EmuELEC, and modding enthusiasts who want an accessible platform for emulating classic games.
