Great Tutorial, But say for example your hacking emerald, i don't know if you know this but They say that emerald has the FR/LG game engine, well i opened it turns out it has ALL the FR/LG maps but there the kind that dont have headers so it looks like nintendo made a mistake and deleted them can ya insert them back in? Also can ya insert new headers?
EDIT: i figured it out what you do is goto header then select the deleted header and walah reopen your rom an there ya have it
P.S: that give emerald some 130+ maps!!!
