Dive isnt an HM, but i can easily change that. The programming for dive is still left over from R/S, so it will be easy to re-implant it back in. Im also planning on bringing the secret bases back, it shouldnt be to hard, since FR/LG was built off of R/S.
Also, how am i going to fit so many maps in? Easy
You see, only 60% of the rom is used, 40% of it is blank data, thats more than enough to put South Rijon in.
Also, all of the gym leaders and main characters (Such as Tim, Brown) are getting a brand new look. They wont be looking like the Kanto characters anymore!
