R40S Pro is a vertical retro gaming handheld launched in 2024. Powered by Cortex-A35 (4-core, 1.3 GHz - 1.5 GHz) and Mali-G31 MP2 GPU. Features a 3.5" IPS display. 3800 mAh battery. Runs Linux.
Inside sits the Rockchip RK3326, with four Cortex-A35 cores running between 1.3 and 1.5 GHz, paired with a dual-core Mali-G31 MP2 GPU at 650 MHz. The platform list starts with Game Boy, Game Boy Color, NES, Sega Genesis / Mega Drive, Game Boy Advance and SNES, and continues with PlayStation. More demanding systems such as Nintendo 64, Nintendo DS, Sega Saturn, Sega Dreamcast and PlayStation Portable are also listed; results there depend on the game and emulator settings, as these are the heaviest systems for this chip.
The 3.5-inch IPS display delivers pleasant colours and good viewing angles, well suited to the pixel art of classic games. The size strikes a balance for a vertical handheld, large enough for comfortable sessions.
The vertical form factor recalls classic portable consoles and fits Game Boy and Game Boy Color titles naturally, giving retro fans a familiar experience.
The 3800 mAh battery provides a respectable energy reserve for this kind of device. The operating system is Linux and the modding policy is permissive, so users can experiment with alternative firmware and custom setups, benefiting from the ecosystem built around the RK3326 platform and the R36S family.
Ideal for: players looking for an accessible vertical handheld for classic emulation from Game Boy to PlayStation, tinkerers who value the freedom of Linux and modding, and anyone wanting an alternative to the R36S with the same retro spirit.
