Hi there, just advising you that New Users/Welcome is not the place to ask for ROM hack help, and your thread will likely get locked.
You're looking for this section:
ROM Hacking subforum in Emulation. There's some helpful threads you can look at.
Also, feel free to contact the Emulation moderators
DrFuji or
giradialkia and they'd be glad to assist you.
Oh, and welcome to PC btw.
