So, I think now there should be no problems using any USB gamepad, in both 32 and 64 bit versions.
Just make sure to run the "ControllerSetup" in the game folder to configure x360ce (the XBox controller emulator) BEFORE running the game.
I also fixed a bug where if you reloaded the weapon from the inventory when you ran out of ammo, you wouldn't be able to attack again until you received damage or enter/exited a room.
Another fix was with the flashlight swapping places upon loading the game.
If you find more bugs, just tell me and I'll (try to) fix it.
