Is there a program that allows me to edit a .GCT file without having to make a new one?

[Hyperstar96]

I have a .GCT for Project M, but I want to add one more code to it. Is there any program that allows me to do this?

And don't say "just google GCTEdit", because every link I've found for it so far is dead.
