So if you plan to do this please stick through till the end.
The possibilities that can be done in the ROM Hacking are many as to copy an idea that others did, that's my opinion honestly do not know anyone says about uu

But anyway, it's your project ... Good luck!
Anyway that's your say and I appreciate it pal, good luck with your project as well
