CoolBaby RS-63 (RS3128)

The CoolBaby RS-63 (RS3128) is a horizontal Android handheld released in 2020 for fans of classic retro gaming who want a simple, affordable and easy-to-use device. It runs Android 5.1, which gives it flexibility and access to a wide range of emulators. The compact plastic body measures 170 x 80 x 18 mm and weighs just 210 g.

It is powered by the Rockchip RK3128, a quad-core Cortex-A7 chip clocked at 1.3 GHz. It is paired with a Mali-400 MP2 GPU running at 500 MHz and 1 GB of RAM. That is plenty for NES, Famicom Disk System, Master System, Game Gear, Genesis / Mega Drive, Game Boy, Game Boy Color and Game Boy Advance. SNES runs well, including Super FX titles, and arcade games are covered through MAME, Final Burn Neo and Neo Geo. 3D PlayStation games run at 60 FPS. Nintendo 64 and Nintendo DS are playable but can be laggy.

The 4-inch IPS display has an 800 x 480 resolution, a 5:3 aspect ratio, around 233 ppi and a 60 Hz refresh rate. It delivers vivid colors, wide viewing angles and a clear picture for classic games. A plastic lens covers the panel, and brightness is adjusted from the menu.

The controls follow a familiar retro layout. A cross-style D-pad sits in the upper position, alongside four face buttons and dual symmetric slidepads. You also get L1 and R1 shoulder buttons, a Home button, a Power button and dedicated volume keys. There is no rumble. Dual rear-facing stereo speakers handle audio, and a 3.5mm headphone jack is there for private play.

Power comes from a swappable 2500 mAh battery that charges over Micro USB. Being able to swap the battery helps extend the console's lifespan. Wi-Fi lets you download apps and emulators directly on Android. Two USB-A ports and a Mini HDMI video output round out the connectivity, so you can hook the handheld up to a TV.

The console has 8 GB of internal storage, and a microSD slot lets you expand your game library. Modding is permitted, so you are free to tweak the system and build your own retro collection exactly the way you like.

Ideal for: beginners and nostalgic players looking for an affordable Android handheld that handles everything up to PlayStation smoothly, with a swappable battery and TV output for occasional big-screen sessions.
