Ok I'm still kind of new to this but I can help with this!
Ok so there are several items that are not used by the game these are named Teru-Sama. It is fairly easy to rename these to the names of the new items you want to make. [keep in mind that anything after Brick Break does not have the proper asm and therefore cannot be repurposed as an evolution item]
So after renaming the teru-sama's you need to set a price for the items and then change the asm pointers to point to the asm used for an existing evo item (say fire stone) and change the description pointers to point to the description for the evo items (once again the same as the fire stone).
You can find all the necessary offsets in the Pokemon Gold Rom map Here: http://datacrystal.romhacking.net/wiki/ … ld:ROM_map
