"Error reading from byte[] data at offset 12543472 data size: 4194304 Please report this."

This translate to getting offset $BF65F0 from the expanded ROM (size $400000). Now this version of FF6LE fetches all needed offsets to work from the ASM code. If a LDA needed is not where it's supposed to be, it will load whatever three bytes there and make an offset with it. There is a ASM verification when expanding, but not when loading a "regular" project. I tried this morning to load a clean ROM and it worked. I'll try again tonight but if I can't replicate this I'd like to see the log.txt file when expanding (even if you don't plan to in the long run). The file would have all the offsets fetched from the ROM. The header is not a problem.

i guess it would be cool to know which banks of vanilla change even a single byte of vanilla rom and eventually which bytes/packs of bytes
can i find an answer like that in a readme or something?

Yes a mini ROM map is on its way!
