Remap keys to joystick

[skod]

Hi. I was wondering if you could map keys to joystick buttons in c64 and/or other micro emulators. I kind of would like to remap controls for certain games to be playable with my 8-button arcade stick. Some games requires space bar, f-keys and what have we, and I really would like to be able to play these using only the arcade stick, giving these games a more natural arcadey feel. Naturally you should also be able to map these at a pr. game basis or it will not make sense.

I cannot find anything on this. Is it possible somehow? If so, please give me a hint on how to proceed.

Thank you.
