I know this question has been asked quite some time ago in this thread, but it was never answered completly. I am very very far into making my rom hack right now, and all of my maps were done and everything until i tried making just one average script. Once I finished copying and pasting the offset in advanced map, half of my maps were corrupted. When I clicked on the corrupted maps, they give me this message: "Invalid pointer to map footer", and:"Invalid data pointer in eventheader on load eventheader". Some corrupted maps only give the first error message, when others give both.
Any ideas on how to fix this? I really really dont want to have to remake my whole entire hack... Even the backup is corrupted.
