Greetings friends and fellow enthusiasts. This is Mikhailov from Team Retrogue where we like retro games and the devices that bring them to us.

MuOS Big Banana is currently in its beta testing phase for KoFi supporters. This version of MuOS will bring support for the newly-released Anbernic RG CubeXX.

MuOS Running on the RGCubeXX

The Anbernic RG CubeXX is a handheld device with an Allwinner H700 processor and a 1:1 720p screen. This makes the handheld perfect for emulating Pico8 as well as Game Boy systems, Nintendo DS, and TATE Mode Arcade games. Let’s take a look at how MuOS handles these specific systems on the CubeXX.

Nintendo DS

Drastic is still in testing, but here is an example of the new “squint-free” menu.

This updated build of MuOS will bring an updated version of the Drastic standalone emulator called Drastic-trngaje. This build is still in testing but will bring a much-needed menu change so we are not squinting our eyes to navigate the menus. Anyone who has tried to use Drastic on a Linux-based handheld knows exactly what I am talking about. Once finalized, there will be some really nice options for DS gaming, including different screen scaling options.

Game Boy

A Super Game Boy enhanced game running on the RG CubeXX with a Pixel_aa shader and Jeltron Overlay.

One of the best use cases for a 1:1 device is for Game Boy emulation, which MuOS offers the best flexibility for. Since the operating system uses Retroarch for most of its backend, you can customize shaders and overlays to your liking. I prefer Jeltron’s Overlays, and I use Russ’s shaders guide to get a really nice, accurate picture. 

Even the 3:2 aspect ratio of Game Boy Advance, with the help of overlays and pixel shaders, looks amazing on the CubeXX.

MuOS also allows the programming of emulator cores per game, so I can use the mGBA core to apply Super Game Boy Colorization for games that support it. 

TATE Mode Arcade Games

1943 is an example of a TATE Mode arcade game you can enjoy on the CubeXX thanks to MuOS.

Nothing too fancy here. The games just look really good on this screen. It’s a simple plug-and-play in this build of MuOS. 

PICO-8

Native Splore support is all we really want, right?

The biggest draw of using MuOS for PICO-8 gaming is native Splore support. If you purchased the proper Pico8 files, you can use the system’s built-in Wi-Fi to browse the Splore library. This test build of MuOS allows you to join a network that doesn’t have a password, meaning you can now log into some guest networks to get your Splore on. 

PortMaster

Downwell is a great port to play on the RGCubeXX.

MuOS is also bringing built-in Portmaster support to the RG CubeXX, and there are quite a few native ports that will run well on this device’s screen. 

You can gain access to the test build by supporting the developers on KoFI. Just keep in mind this is a work in progress, and there might be some issues that have not been finalized or ironed out yet.
