Remote retropad display update
Browse files Browse the repository at this point in the history 
Refine the display for Remote RetroPad, as a preparation for
using it as a test tool:
- added display for analog axes
- all inputs that were hit at least once, receive a light green color
- removed useless extra button (could never be sent)
