Still trying to desperately figure this out, I took a look at the 'Manage expanded ROM' section in USME,
and noticed this -
FF3Edit Map Graphic Expansion
HOW AN EXPANDED ROM WITH WORKING OVERWORLD MAPS IN LE LOOKS:
Regular section usage:
WoB Map/Tiles: $EED434-$EF324F, 24092/24092 bytes
WoR Map/Tiles: $EF4A46-$EF9D16, 21201/21201 bytes
Mini maps: $EFE49B-$EFED25, 0/2187 bytes
HOW MY ROM LOOKS:
Regular section usage:
WoB Map/Tiles: $EED434-$EF324F, 24021/24092 bytes <-------- missing bytes
WoR Map/Tiles: $EF4A46-$EF9D16, 21201/21201 bytes
Mini maps: $EFE49B-$EFED25, 0/2187 bytes
So in the WoB Map/Tiles, there appears to be some tiles, or bytes that are missing?
Could this be what is causing LE not to show the maps and all my grief??
I then copied the data from the working expanded ROM over to my hack, and opened LE and sure enough, it showed the maps again! OMG, I got so excited, but then when I went in to test in-game...the game becomes corrupted upon showing the overworld maps. It either just goes all black, or some really messed up tiles everywhere.
Sooo with my data how it is in my hack, the overworld maps are uneditable/don't show up in LE, but work just fine in-game. But if I copy over how it original should be, it shows the maps in LE fine, but corrupts my freakin' ROM.
Not only that, but then when I checked in
FF3Edit Map Graphic Expansion again, it showed:
WoB Map/Tiles: $EED434-$EF324F, 15643/24092 bytes, so that's why the corruption obviously, transfering the data over somehow made tons of tiles and bytes vanish, but it fixed LE being able to show and edit the maps...huh.
I am at this point very confused, but have not given up, I feel like there's still hope.
ANY more insight into what may be going on or an idea how to fix it still would be most welcoming.
I'd much love to resolve the issue, and be able to edit the overworld maps once again.
