So Here the research thread for Ghost Marowak.
I've seen a video on Youtube of guy who claims Ghost Marowak can be caught be modifying the RAM of your save at CFDA according to him.
CFDA corresponds to the Name of your opponent according to the Map but yeah it can be something around. Or the ROM to modify?
Here's my sav for those who wants to search with me but are lazy to begin a new adventure just for the event.
My theories: maybe the type of battle D057 or battle type D05A
