Fixed it - was a stupid class overriding bug - the big endian detection got ignored. I'll upload new version later.
I've tried it with the demo versions of xbox mi1 and 2 that I was sent and it opens and works perfectly with both when XBDecompress has first been used to decompress the pak file.
[Edit] Done - see my site for the new version.
