Excellent Rom Hack..
Is the item "Macho Brace" available in the game?
edit: Found Macho Brace in Tyron.
Here some Bugs that I found:
1) Only 2 town are flyable in Tyron, Marble City and and Mugwort Villa.
2) Pine Tower Not accessible
3) Plume Fossile give me Cranidos, going in and out, infinite cranidos from the plume fossile.
4) Sky Castle --- Not sure if this is a bug, but it's useful bug. It is really funny and useful at the same time actually. (Genesect Room Work the same)
--- Everytime You go to Sky Castle, (even after the event) by going to the mini room at the first area (where the Team Mirage minions are), it resets most of the game play... Therefore You can get unlimited Nugget (right side room by the entrance), aka infinite money just by going in and out. It also reset some of the trainers, items (infinite rare candy, infinite TM), hidden items, gym leaders, and who knows what else.
