The directory is created automatically when you start the app, so there’s no need to create it yourself. You can also have subdirectories in the latest version and they’ll show up in the file browser too.
I restarted my playdate and it seems to have worked, the directory was there, it just wasnt finding the mod files I added, initially the mods I added were not showing up in the ram disk, now they do after restarting the device, thanks!
