Hmm... I'm having trouble completing part 1. On step 14, when I need to reinsert the edited "overlay9_0167.bin" file, CrystalTile 2 comes up with the error, "file is too small!" and tells me to relocate the data. I checked to see if I had the same issue as Scooters, but I checked my edited overlay file in HxD, CrystalTile 2, and in Properties, only to find that the file is 268544 bytes, which is exactly what it needs to be. I double-checked the "distribution Overlay file location and space" to make sure it had "02199700,268544", and even though it did, every time I tried to import the file using the "Compression" Option, I got the error. I'm not sure what I'm doing wrong, the edited file is the right size. I used HxD to edit the overlay instead of CrystalTile 2, that's not a problem, is it?
EDIT: The same thing happens when I try inserting the edited "a/0/1/1" file. It seems that every time I try to import a larger file, it comes up with the error. I don't know what to do.
