is on the menu above called "search"
But seriously , what joystick is it and you really shouldnt need software. Depends are you modding this joystick or just not sure how to assgin buttons ?
more info would be helpful
LFS does not support using a joystick as a shifter. for that you need a tiny bit of software.
I hope i don't upset the author but I've attached the program you'll need. you can also get one that supports force feedback, but you'll have to search for that. it's called FFshifter or something similar.
good luck making your shifter dude. you'll find getting a decent H-gate the hardest bit, but it's well worth it in the end!
