BOYHOM R40S is a gaming handheld launched in 2024. Powered by RK3566 (4-core, 1.8 GHz), 1 GB RAM. Features a 4" IPS LCD display (720 x 720). 4000 mAh battery. WiFi 5. Runs Linux.
Under the hood is the Rockchip RK3566, a quad-core Cortex-A55 chip running at 1.8 GHz, paired with a Mali-G52 2EE GPU at 850 MHz and 1 GB of LPDDR4 RAM. This combination comfortably covers classic systems such as Atari, NES, SNES, Sega Genesis / Mega Drive, the Game Boy family and the original PlayStation, along with arcade titles through MAME and Final Burn Neo. Nintendo 64, PSP and Dreamcast games are mostly playable but not all run at full speed, so demanding titles may need some tweaking.
The 4-inch IPS panel runs at 720 x 720 with a 1:1 aspect ratio, about 255 ppi and a 60 Hz refresh rate. The square format suits retro games that were never designed for widescreen, and the OCA-laminated tempered glass lens adds protection and clarity.
Controls include dual thumbsticks with L3/R3 in an asymmetric layout, a cross D-pad in the lower position, four face buttons and horizontally arranged L1, R1, L2 and R2 shoulder buttons. Dedicated power, reset and volume buttons round out the layout. The plastic body measures 145 x 86.5 x 10 mm and weighs 211 g, although some users find the buttons sit too deep in the shell, which affects their feel.
Power comes from a 4000 mAh battery, charged via two bottom-facing USB-C ports, with USB-C OTG support. Connectivity covers WiFi 5 and Bluetooth, while a top-facing Mini HDMI port lets you play on a TV. Audio is handled by bottom-facing dual stereo speakers and a 3.5mm headphone jack.
The R40S runs Linux, modding is permitted and dual microSD slots make it easy to keep the system and game library separate or try custom firmware.
Ideal for: retro fans who want an affordable, pocketable Linux handheld with a square screen, dual analog sticks, TV output and broad emulation up to PlayStation, with occasional forays into N64, PSP and Dreamcast.
