This is a small tool I created some time ago primarily to learn assembly programming for the C64 home computer. It has been sitting on my hard drive for several years, and now I've decided to upload it to itch.io. Perhaps someone will find it useful.

I've encountered numerous issues with my joysticks, which led me to rely heavily on this tool following my attempts to service them.
