MCGamepad is a small Forge mod that uses the LWJGL JInput bindings to provide gamepad controls to Minecraft. Currently the mod only correctly XInput-like controllers (including those provided by the ScpServer PS3 and PS4 bluetooth controller interface on Windows) and has no button reconfiguration options. The mod is being developed for the Forge beta for 1.8. Forge for 1.8 is required.
You can use the mod on any platform that JInput has modules for, but the mod is only tested for Windows. Future versions may alternatively use an XInput binding for rumble support on Windows.
