@multiSnow This is great, thank you so much for this! It's been a busy few weeks and I've haven't been able to make time to do this myself, so I really appreciate the effort.

Looking at the SDL2 changelog, I noticed that 2.26 adds a bunch of new hints for different things (e.g. SDL_HINT_JOYSTICK_HIDAPI_XBOX_360). Would you be willing to add these to sdl2/hints.py? Once that's done I'll add some brief tests to the test suite for the new bindings and get this merged. Also, feel free to add yourself to the AUTHORS.txt file now that you're a contributor!

I'm going to merge this into my own 2.26.0 branch to add a few more odds and ends before merging into main (e.g. event structure changes in 2.26.0, some unit tests for the bindings), but that should be short work with everything you've already done. Thanks again for the PR!
