Why does none of this code work on big endian mips ?

Is it difficult to make it work ?

Is it certain that the "disabled" code does not work on
big endian mips ?

Is it known that the reason for it not working is the endianness or
could it be a unrelated issue that makes it work on neither endianness?

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
would be bankrupt already.
