About not being able to use the gamepad

I did some research on the issue of not being able to use the controller.

I found that if the Steam controller setting was set to [Enable Steam Input], the controller would not respond.

RUMBLE BLAZING is compatible with XINPUT type controllers.
If it doesn't work with a XINPUT controller, try the following.

Right-click [RUMBLE BLAZING] from the Steam game list and select properties.
Please select [Disable Steam Input] from the [RUMBLE BLAZING Override] setting in the properties controller and try launching the game.
