Hi, its awesome to know in launchbox how many times you played but it would be more detailed if also show how much time you spent on the game. I know i know there's already some topic talking about it, but was concluded as imposible.
My suggest is take advantage of some emulators logs for runtime like Retroarch with its addition to have runtime logs to show Played Time. so with this launchbox doesnt need to integrate with the game and just take advantage of the tools provided by retroarch in this case the runtime logs ,knowing an emulator will have always direct interaction with the game and so have this opportunities to get the played time.
