With that being said, while the positions of repeat levels is hardcoded into the EXE, their stats / titles / etc are not - those can be found in (assuming the DOS version) oddtable.dat. If I remember correctly, oddtable's format isn't documented anywhere, but it's also very easy to figure out if you know the LVL format already. The order of levels in oddtable.dat correspond to their order in the levelXXX.dat files, including placeholders for non-repeated levels; and the file is not compressed.
