-Actually, as it happens, '''Settings/rb.gamedata''' is the file whose data, at 0xE5000, is the one that comes first, and between it and the preceding string data there are 1866 bytes of unneeded space. Together with the 297 bytes of the file itself, that allows for 2153 bytes of plain text, which is enough to list a lot of the layouts, if not all of them.
