This is something I wanted to do for a long time. Sentinel is my goto game what I play at least once every year I just wished for a better/easier dogfight, and even mouse support.

I've collected data about how the C64 handles mouse and actually the mouse driver itself not that big, I bet it can be added rather easily to games even with my limited assembly knowledge (however maybe not worth it as only few have the hardware).

I read that everyone disassembling their favorite game in the last two weeks so I gave it a go as well, used Claude - otherwise I would never complete this fun project - so please be easy with me. It now fully playable with mouse only (map and torpedo mapped to the mouse buttons), it still gives a challanging but fair dogfight, a more difficult navigating in warp space (with JOY you can just push down or up all the time and you are safe, with mouse it's not that easy), and a bit clunkier map navigation (you just don't see where are your exact cursor position, misclicking on the map)

No download link, as I'm not sure if I want to publish it and if yes then where (CSDB Maybe?)

Looking for a good not overly expensive joystick to use as currently using the master system gamepad which is okay but doesn't respond and is getting me killed alot
