I only have Star Fox 64, but why isn't there a sticky here saying what n64 buttons correlate to keyboard? It seems like x=a and c=b, but what are all the others?
You know, usually in this situation any self-respecting user would take a glance at the User Manual, which just so happens to be included with Project64.
Documentation included with emulators is never some random filler junk which can be ignored. Surely you realize this.
