Apparently, changing FFTA.sys to Lioneditor.bin is no longer working in the Lioneditor program. Anyone else experience this issue, and if so, do they know how to fix it? I haven't seen anything in the forum yet. Maybe I overlooked something?
Did you try spelling it "lioneditor.bin" rather than "Lioneditor.bin"?
Other than that, make sure it's an unencrypted save.
