Leet Sketcher: Thanks to Headerizer, I can easily change the patches to whatever I need. I just need to know which way to go. :3
Yeah, I know, but you wouldn't have to if I'd done that for you, which I should've done because I'm the one who made that patch.
I'd love to know what program/documents you use to edit the maps of the game without having to change the compression. I was unable to edit the Phantom Train chest in the past.
Sad to say, I just used a hex editor. I'm pretty sure darkmage used either Zone Doctor or FF6LE; the thing is, those programs do an OK job of recompressing, but the algorithm used isn't perfect and certainly doesn't compress as much as possible. I, knowing the compression format, and knowing where the pointers are to the correct tilemap configurations, can generally find the tile(s) I need to change using some searching and mental math. After that, sometimes it's an easy fix of just a byte or two, other times I have to work stuff around, collapse pointers and whatnot to make everything fit.
One thing that happens as a result is that some of the maps suffer from side effects, but I generally try to make them ones that aren't noticeable in-game and don't affect the game at all (i.e. the only way you'd know they're even there is with an emulator with BG layer toggling).
