You must be missing a library. Or you need the updated "input.library". You can usually find on the game discs themselves. When I installed the SX-1 and Kickstart+Workbench 3.1, I always checked my game disks for newer libraries than the original 3.1 install and copied them into the appropriate Workbench drawer.
I might have had to add something to the startup-sequence as well. I forget and my HDD is iffy.
