Hi all! I finally got my MakeCode Arcade machine working with a RaspPi Zero and arcade joystick + buttons! But I can’t seem to add my own games. I noticed that the default games it comes with are in .elf and when I try to download my games on Makecode, it’s downloading as .uf2. Which format does it need to be? And should I be putting it into a folder or just the root of the micro sd card? Thanks!

I have the same problem, the games need to be elf but always download a uf2.

Don’t know if you ever found a solution, but I did. Here is the link to download the games as ELF files.
