OpenBSD Live Port Hacking: Godot 3 SDL3 gamecontroller backporting (2)

Watch me try to backport the newer Godot SDL3 gamecontroller driver to the OpenBSD port of Godot 3. This will use Godot 3 game Brotato to test the controller layout. This is the continuation of the original work. UPDATE: it took a bit of wrangling with API changes from Godot 3 to 4, but I have a working diff which will soon (as of May 30, 2026) show up on OpenBSD ports@ mailing list.
