This is the case on both 1.2.2 and 1.3.0 (which I downloaded in the hopes of solving this problem).
I’m using an Xbox 360 controller. Out of the blue today, it started acting like I had all the buttons on turbo. Even the start button acted like it was on turbo. I saw no option to turn turbo off (or on even, for that matter). Setting the “turbo period” and “duty cycle” to 1 make the controller function normally, but that leads to two problems of its own: the word “null” keeps appearing on the bottom-left corner of the screen every time I press a button, and the game won’t remember the configuration, so I have to manually make this change every single time I start the program, or even change games!
What is causing this problem and how can it be fixed?
