Some help with sm 3.9

[awesomebox]

So my computer froze and had to shut it down but my sm settings got completley messed up the c mods i added are mostly gone, the arrows are no longer centered when in 1 player, and my ridiculous timing mod no longer works
So basically what i need help with is
Finding how to add more speed mods in the settings folder
Figuring out how to put the note receptors in the middle when in 1 player
Reinstalling ridiculous timing

I know 3.9 is out of date by over 14 years i just like how it functions and the ridiculous timing is cool too i am aware of judge 7 and how to do that i just perfer the mod
