I have some experience in working of engine which uses 2 data sets with
different byte order, i.e. SAGA. I can tell you that this task will
require to review every structure in the engine. As I see, now sword1
engine uses direct reading from File with use of readXXXLE() family of
functions. This will not ease your task, as earlier it mapped data
directly into memory chunk pointed as a structure. To achieve similar
goal in SAGA, we used MemoryReadStreamEndian wrapper (see
enignes/saga/stream.h), which could be set to read either BE or LE
format without adding hassle to the source. So you'll have to use
something similar.

This is not difficult at all and, say, I could add this if needed.

No.

Several peoples asked about it in last couple years, all of them were
suggested to buy PC version.

Mac version is rarer than PC version and AFAIK, it has no advantages.
But of course, if you are willing to work on it for the sake of
completeness or personal amusement, I wish you all success.
