KoHotech Ritmix RZX-50 is a gaming handheld launched in 2011. Powered by JZ4755 (1-core, 400 MHz), 64 MB RAM. Features a 4.3" TFT LCD display (480 x 272). 1800 mAh battery. Runs Linux.

The KoHotech Ritmix RZX-50 is a horizontal handheld launched in 2011 and now discontinued. It is built around the Ingenic JZ4755 SoC, which uses the XBurst architecture on the MIPS instruction set, with a single core at 400 MHz and 64 MB of DDR2 RAM. It is a modest platform aimed squarely at classic emulation.

The platform list is generous: Atari 2600, ColecoVision, Intellivision, CHIP-8, NES and Famicom Disk System, Sega Master System, Game Gear, SG-1000, Genesis / Mega Drive and Mega-CD. It also covers PC Engine and its CD variants, Game Boy, Game Boy Color, Game Boy Advance, Neo Geo Pocket and Neo Geo Pocket Color, and Watara Supervision, plus Final Burn Neo, MAME and ScummVM. Most SNES games run at 60 FPS, but FX and Mode 7 titles lag. Many 2D PlayStation games run fine, though not all at a full 60 FPS, while 3D titles struggle.

The 4.3-inch TFT screen has a 480 x 272 resolution, a 16:9 aspect ratio, 128.3 ppi and a 60 Hz refresh rate. It sits behind a plastic lens.

For controls, you get a cross D-pad in the upper position, four face buttons and L1/R1 shoulder buttons. There are no analog sticks and no rumble. Hold and Reset buttons, a power switch and a microphone round out the hardware, while volume and brightness are adjusted through the menu. The plastic body measures 182 x 80 x 15 mm and weighs 192 g. Dual stereo speakers face the front.

The battery is rated at 1800 mAh and charges over Mini USB. The device also offers AV video output, a 3.5mm headphone jack and 4 GB of storage on microSD.

The operating system is OpenDingux, a Linux-based distribution that gives access to community-developed emulators and applications.

Ideal for: collectors and fans of vintage handheld hardware who want to play 8-bit and 16-bit games, Game Boy Advance and classic arcade titles on a widescreen display with front-facing stereo sound.
