Color continuity with sprite ripping

[Garamonde]

Well, that's why you can change it in the Hotkey Config under Config.

But seriously, try changing them and they should work. Remember, each time you press the key makes the game go slower or faster by a certain amount (and it is noticeable once you press it a few times), it doesn't work like fast forwarding where you just hold the button. I'm not sure what else to say, it works for me (I have "Increase Speed" set to "R", and "Decrease Speed" set to "T").
