Description

Hello. Can you add the option to have a 1:1 customized button mapping for controllers with enough buttons?
I have the retronic adapters that allow using the standard intv controllers. The adapter treats the 1-9 keypad as separate buttons, not an analog stick, so cannot use the diagonals 1,3,7,9 with freeintv. I can use all other buttons by mapping the controller buttons using your scheme (e.g. map 5 button to rt). Thank you

edit: I was able to hack the code to force 1, 3 , 7, 9 to start, select, left, right. Basically works, but needs some fine tuning .

Research direction

No source files, tests, or entry points are named. Start by tracing FreeIntv's existing controller-mapping scheme and how keypad buttons are exposed, then compare it with the retronic adapter's separate 1–9 inputs. Done means an optional 1:1 mapping supports those buttons without breaking the existing joypad mappings, with coverage for the diagonal-key behavior.
