[**2021.01.26:**](https://github.com/Vegz78/McAirpos#installation) Got tired of doing the manual installation procedure on all my test images and made a quick automatic installation script for everyone to use.
[**2021.01.24:**](https://github.com/Vegz78/McAirpos/commit/c1350073bc3ba21be16c098a44f46469a3658fd4) Stability improvements for game launch and exit, more accurate keyboard autodiscovery, defaults to lowest keyboard input event handler, new ```keybswap``` command line option to swap to highest.
[**2021.01.18:**](https://github.com/Vegz78/McAirpos/commit/932740f491cf1afede31578a6077f6ab5c2994f8) Bugfixes, improvements and further testing, most notably fixed the occasional mismatch of /dev/input/eventX between uinput-mapper and launCharc in /sd/arcade.cfg, and now possible to map 1 & 2 controllers without keyboard connected. Feedback about additional working controllers and about possible reasons for occasional instability/game exit, especially on older RPi devices and RPi OS/RetroPie distros, is still appreciated.
