@garbear The current code works perfectly fine in retroarch (analog controls reported in "quick menu > controls" + they work as expected when playing).

If lakka behave differently than retroarch about this, then this is surely a lakka issue.

I want @fr500 and @twinaphex opinion on this before merging it.

This is probably about kodi's retroplayer. He's right, seems his player is more compliant than ours :P

[barbudreadmon]

Ok then, i hope no issue will appear from this change.

[andres-asm]

Shouldn't cause any issues

Thanks for merging. I built a project around libretro input called the Controller Topology Project. It's a database of controller data that Kodi uses for zero-config input. We also rely on libretro input data, and noncompliances breaks the autoconfig process.
