There's no icon/header info. Only a banner. Launching it just displays an error screen.Works fine for me. Here's my CIA build: https://github.com/Cruel/scummvm/releases/download/3ds/0.1/scummvm-cia-0.1.zip
Let me know if it works okay, I need to fix my EmuNAND as it's not showing installed CIAs on menu lol, but it launches fine from FBI.
Yes, it needs all included files in /3ds/scummvm/ and it will remain that way. (it also stores the .ini config file and game saves there)
