I'm using a generic SNES to USB adapter and an original SNES controller. I had previously successfully bound Break to L, which it registered left bumper. Played a few races that way, then wanted to try swapping buttons. The moment I pressed L to bind it for Accelerate the game crashed. Now it crashes whenever I go into the "Configure Controls" menu.

- I tried reinstalling, but it kept my profile.
- I tried making a new profile, but it kept the key bindings.
- I tried resetting the settings to default, and it let me enter the Configure Controls menu. Keyboard binds were displayed, but when I pressed right to change to controller binds, it crashes.
- Have tried disabling steam cloud and reinstalling. Problem persists, doesn't even erase my profile.

Solution: I managed to find the config file location. %APPDATA%\ansdorGames\Slipstream\
Deleting 'controls-1.2.bin' and relaunching the game worked. Was also able to re-bind acceleration to L (left bumper) and it works fine now. No idea!
