I’ve had the charge limit on 80% since it became available as I leave my deck docked for long periods of time, but it doesn’t seem to be working since every time I get it away from the dock it shows 100% charge. Also the charge indicator gets stuck now until I reboot the deck, but that’s a separate issue…

Playing through the third one right now, the first 2 ran great already, and the launcher really is convenient, before it was all manual commands in the terminal.
One advice I would give is to delete the rom file and the iso_data/{gamename} folders after the games are fully installed to save space, since it’s several gigabytes per game that are not used after the installation
Some of the directories are in the home (the tilda ~ means home of the current user) and home directory is not immutable
