New version on the repo!
You can now select more than one game at the same time. I set a limit of 10 simultaneously loaded games though, to avoid running out of loopback mount devices (there are 15 available, but you need one for this PND, one for the music player PND, and I prefer to keep a few spare ones so you can still mount some more PNDs).
You can also select the music player: you can choose between Audacious, DeaDBeef and Audiorace. Audiorace only works for some games at the moment, and it will only load the first song of a game. Maybe crow_riot will release an update to Audiorace at some point to change this.
Three more games were included: Gweled, SuperTux, and Wizznic.
I tried those visual novels by ED but they put all their data (including the music) in some weird archive file called "arc.nsa" and I have no idea how to open it. I didn't buy Super Hexagon, so I don't know where its music is. If someone can give me the path to the music and the filename of the .desktop file for it in /usr/share/applications, then I'll add it.
