Maybe it's still not clear, let me know and when we figure it out I'll improve the guide

(2020-02-28, 22:40)garbear Wrote: OK, I see what you're saying now. The difference in behaviors is because a playing game acts as a "filter" - only controllers supported by that game are shown. See: https://github.com/xbmc/xbmc/blob/master/xbmc/games/controllers/windows/GUIControllerWindow.cpp#L210 . It looks for an active game client (libretro core), and passes that to the controller list if discovered.

So assume the controller window knows which core is active, how does it know which controllers to show? That is determined by a file named topology.xml which you can see here: https://github.com/kodi-game/game.libretro.dosbox/blob/master/game.libretro.dosbox/resources/topology.xml

topology.xml defines the "controller topology", which is a tree with the console as the root, and the supported controllers as nodes. For more information, see the controller topology project: https://github.com/kodi-game/controller-topology-project

The image that says "nothing to map" is concerning. Why is that list empty? That might be a good first bug to track down.

(2020-02-29, 22:09)garbear Wrote: Yes. Does your second picture show that is not the case? If you post a debug log, I might be able to see what's wrong.

(2020-03-02, 09:21)cool-pants Wrote: I figured out what was wrong. Apparently this bug only occurs when we run a game that is not compatible with the emulator engines, for the above case DOOM, which I downloaded separately.
But shouldn't we display a not compatible message for such games rather than let them run.

(2020-03-09, 11:32)cool-pants Wrote: Excuse me @garbear  i checked the debug log to figure out where the game is actually getting stuck at, i.e. is it during creating an instance of the game client or while actually trying to run the game.

(2020-03-09, 11:32)cool-pants Wrote: Also i am simultaneously looking into mapping of multiple controllers onto the game, so i had a doubt, do we allow multiple controller mapping and use during the game client is running or do we want the multiple controllers for the kodi interface as well. Personally i think the former makes more sense, but please advise.
