Hi everyone, I'm new to rom hacking and have learned a lot from people kind enough to post tutorials and from tinkering with advance map.
However I'm having issues with adding blocks to a tileset so I can add my own tiles to it. When I change the amount of blocks to tileset 2, the behavior byte and backround byte of all existing tiles that I wanted to use in tileset 1 are wiped out to 0 and even if I set them back to the way they were they either respond or don't. Any ideas of whats going on or if I'm handling this the wrong way? Thanks in advance.
