MiyooCFW VS gb-studio

Try getting a second SD card and flashing it with the Miyoo cfw from here. It's probably something corrupted on the card.

And/or just install one of the nightly builds yourself and see what issues you find. They can be found under the actions tab on github, although I think you have to be logged in to actually see the download: https://github.com/TriForceX/MiyooCFW/actions/workflows/build.yml

Generally speaking RetroArch allows installing and removing cores, but no clue how it works on this device and what the steps are if its possible. This article or tutorial might interest you: https://github.com/TriForceX/MiyooCFW/wiki/RetroArch-Setup I think you should be able to download a core from this place https://buildbot.libretro.com/nightly/dingux/miyoo-arm32/latest/ and just put it into the cores folder in RetroArch on your device. But there might be additional steps needed to integrate them into the system, not sure at this point. BTW you should have added the name of the device into the post title. Such generic titles aren't helpful.

I have used already the cfw for this model https://github.com/TriForceX/MiyooCFW/actions/runs/4988520114

GB-Studio (MIT/C) https://github.com/chrismaltby/gb-studio

I doubt it was intentional. They hired a studio to make a retro style game and they probably just happened to hire one specializing in gb development. There's a lot of good tools now like https://www.gbstudio.dev/

👾 Software - GB Studio. I spent a large part of my childhood playing Tetris and Micro Machines on my Gameboy. Now anyone can create Gameboy games with a drag-and-drop editor.

Very cool! Maybe you can make a pixel art style portfolio of your work that runs on a GB cart and a rom to share around? Do you know about GBStudio?

No, it's an actual game boy game built using GB Studio, that's the point, that it's compatible with any device capable of running GB games, including original hardware! :)

It actually does interpret bytecode, you can see the opcode definitions here https://github.com/chrismaltby/gb-studio/blob/1f995a976bd3aa...

The trick is that a lot of the heavier stuff is implemented in assembly and this is mostly used for lighting scripting (from what I understand).

Me when gameboy studio exists: https://www.gbstudio.dev/

If you ever want to just play around with gameboy stuff, GB Studio is much simpler, but only supports building certain types of games, since it's a no-coding kind of thing.
