I won't teach you. I don't have the time for it right now. But I can point you in the right direction. You need a Fire RedROM. You need AdvanceMap 1.92, XSE, NSE 1.7, NSE 2.0, HTE and several other software tools and probably a Hex Editor like HxD. And you need ideas, free time, dedication, patience and willingness to learn. There's a bunch of tutorials on this message board that can help you figure things out.
Good luck. Thanks for playing my hacks!
