Map 2 keys to one button?

pretty simple question

for example, i want to map the jump button to buttons 14 and 12 on my gamepad.

is it possible?

TIA

not directly, no. You can have up to one button and one key mapped to the same retropad button, so if you use something like xpadder to map one of those physical buttons to a keyboard key, you could then map the retropad button to both of them.

This is exactly how I get dual Z triggers for N64.
