Speaking of which, I'd love to have a version of r/SBCgaming in here. The incoming RK3588 devices will be incredible.

Honestly, the entire SBCGaming subreddit needs to make its way over.

Pretty sure it’s the RG35XX? Right?

Ambernic model RG35XX

You can play it directly out of the box, but there are custom OS's out there that run things even better and add more features. You do supply the ROMs, but there are plenty of ROM packs out there too to make your life easier. I honestly recommend looking into RetroGameCorps on Youtube, he has some great content around these types of devices.

If you get the RG35XX specifically, I'd recommend this guide.

The screen is indeed very nice.

Like not even close. This is like 5th generation consoles and no PC. Aya will emulate Switch and probably lots of PS3, and of course play PC games. Also it lacks a 3D joystick so there's that.

I can only see one post there?

Hundreds, if not thousands, across all kinds of retro consoles! Atari all the way through Gameboys, NES up to PS1. The default OS seems ok, but I only tried it briefly before switching over to GarlicOS which everyone seemed to be keen on. This guide was super helpful in getting me started.

I don't know if it has midi support but it does work with LSDJ! That's exactly one of the reasons why I got it myself :D

In order to do that you'll need to first change your /CFW/skin/settings.json to have "text-alignment": "left" and "text-margin": 300 to shift your games list to the right. Next you'll want to use a tool like Skraper to generate your images so it is transparency on the right where your games list is and put what you want to display on the left. You can use the image mixes provided from ebzero on Github or the 2 image mix with only the gameplay screenshot and box art that I've modified below and place the xml into the Mixes subdirectory of Skraper:

When you've decided what you want to use, find the Media Type option under the Media tab in Skraper and choose User Provided Mix and then you can select the custom xml file you want to use when running Skraper.
