Feature Request Display Current Mapping as a Control Test

[EkDor]

Feature Request. I've searched for anything to this effect but found non.

Would it possible for someone to write a utility to display the current mapping as a control test? Personally I'm just thinking I would like one for the arcade cabinet use where there is not a million functions. Pp/down/left/right buttons 1-10, coin and player for player 1-4. I have a pretty basic setup of 4 directions, 6 action buttons each plus 2 coins and 2 player button. The cabinet also includes reset power, reset core and service/menu buttons, but they are handled by the FPGA, so they are fine.

I just ran update_all for the first time and saw it installed a controller one that would do most of what I requested.
