Yea, the add-ons need to be compiled in a separate build step. You'll want peripheral.joystick, game.libretro, and game.libretro.nestopia. I documented the various ways to compile the add-ons in their Readmes.

I think you can build multiple add-ons at once, e.g. cmake -DADDONS_TO_BUILD="peripheral.joystick game.libretro game.libretro.nestopia ...

On OSX I do cd tools/depends && make -C target/binary-addons ADDONS="peripheral.joystick game.libretro game.libretro.nestopia"

The cluttered "games" submenu is a bug in the skin XML, i think the skin includes got messed up in the last rebase. too lazy to muck around with the xml it was basically a c/p job from another part of the xml

Heimdall is still on the menu. Heimdall itself is relatively advanced, scrapers are written in python declaratively and the inference engine figures out which scrapers to use for the various fields. Integrating this into Kodi will take some work.

Also, key mapping is incredibly primitive ATM. Press "t" to open the controller configuration window and map keys or joystick buttons. Some pictures are missing. The buttonmap is saved to userdata/addon_data/peripheral.joystick/buttonmap.xml, but there's a bug loading it so restarting Kodi will lose all your key mappings. have fun until i fix this bug
