minUI-arcade-filename-converter VS MiyooCFW

You can use something like this https://github.com/hyongju/minUI-arcade-filename-converter/

Probably easier to fix the mame.csv. I have used https://github.com/hyongju/minUI-arcade-filename-converter/ for my files for usage with MinUI and still had to rename quite a few by hand which took me an evening or so but might be an alternative if intend to shorten the names anyway.

Hi I've generate a python script to be able to rename filenamea automatically. Feel free to checkout https://github.com/hyongju/minUI-arcade-filename-converter It is a bit involved process as you need to install python and libraries!

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
