Hello,
RetroGames AIO is a simple launcher that allows you to get game data and cover art from thegamesdb.net.
Paths are being saved relative to the launcher path, so you can move your whole collection around.
PLEASE NOTE: The game folders have to be in the same folder as the launcher executable. You can put them into a sub folder like "Games".
