Item description:

This hack makes up four new evolution stones for trade evolving Pokemon. Copies of the already existing items Ruby, Sapphire, Dragon Scale, and Up-Grade are made using already present and/or dummied out existing data, meaning no free space is used outside of relevant modifications. There is a version for a clean Emerald ROM, and one for both of my Emerald hacks that uses decapped item names and modifications made exclusively for it.

Also effected are a Mart or two and some Wild Pokemon’s hold items.
