do you have twitter or discord??If it's just about you not knowing when you do with a gscr, you can inject it GSC Studio (or whatever else injects those retarded files) and then grab it from your Xbox's memory location 0x40300000. It'll be there as a game script.
Then you can take it to a decompiler or whatever.
Or if your problem is just about generally not knowing how to succeed in any kind of decompiling, you'll have to hope someone will do it for you :l
