Hello! I would like to see if I can hack Yggdra Union for the GBA, starting with the graphics (particularly importing my own sprites and character portraits). I've opened my ROM in both TileLayer Pro and NLZ-GBA Advance but have not been able to find anything recognizable aside from what might be a few map tiles in NLZ-GBA Advance and some very fragmented scraps of character sprites in TLP. How can I make it so that the graphics appear in at least a somewhat coherent fashion?
Also, I'm trying to figure out how to edit in-game text and possibly also edit the levels but am not sure where to start for those (hex editing of each individual letter and map time, I'm guessing). Any pointers on how to get off the ground would be much appreciated. Thanks in advance.
