We are not sure... but some games have been fixed by replacing the CDVDSTM.IRX file.... and this is what I've been testing.. but looks as if this is not the case for it....
I'd like to test this LBA... and see if this would fix it...
It has a tendency to lock up at random... I've played though it about 2 hours on each copy... then it locks up after reaching Empire... although not always in the same place... which is a pain in the arse...
