Thank you for the kind words, Blues. There is a way to configure the keyboard in Pico-8. It is saved in the confix.txt file. This also works for the downloadable versions.

But the tool to change the key config is not properly exposed to users. You need to edit the config.txt file by hand. If you have troubles feel free to ask in the lexaloffle.com forums or on our Discord
