First of all huge thanks to Devs of LibRetro :).
I have been searching for support of wireless keyboard and mouse in Libretro. I want keyboard because i can bind more number of keys and get double player support at-least in a single device and have been playing platformers with KB.
Can some please share if they have used wireless keyboard and its compatibility over different version of android? Is the dongle provided with KB required to work (via OTG mode). Dongle requirement will kill my plans.
keyboards i will buy if support is possible -

PS: I am a developer and have made Bluetooth stream based input mapper, Connected My Old Nokia phone with android and sent key events to my android app. Would work on retroarch src to get the same to work with.
Thanks
