How to edit controls?

[Grunker]

I just installed Project64, but I can't find any way to edit the controls. I remember from later version that this was possible. Have they removed this feature, or am I missing something obvious? If they removed, then why?

..did you tried all the configuration menus?

I did, no luck. There's no option to edit controls:(
