>mapped to a game's joystick(s).
Aha. I think therein lies the misunderstanding. I am not trying to map inputs. No arrogance intended at all, but I do know how to map inputs to connected devices in MAME. Rather, I am trying to map sensitivities to an already successfully mapped input. The sensitivities I am trying to apply will make an analog 2-axis thumbstick behave a lot more like a digital 8-way joystick. Meaning, that MAME will not register a diagonal input unless I push the thumstick all the way into a corner. Can anyone else who is familiar with joystick mapping and MAME assist with this please?
