Configuring joypads to send keyboard events isn't that hard - just run System Preferences, select USB, find the joypad among the available devices (it has to be connected obviously
and hit the Settings (or so, I don't have a MorphOS machine with me atm). Afair the available buttons are in the last tab. There you can select a certain joypad button and assign actions to it. For keyboard hits you should assign both key down and key up events afair.
