h.sie,
thanks for educating me, I was sursprised that someone with as little computing skills as me could follow this demonstration. Struggled at first with step 7 as that was especially tricky.
Its a shame that I had to delete the amended file rather than use it but I wouldn't want to break any copyright laws.
Thanks to your great work, should the copyright laws change or Ubi chaneg the copyright status of SH3, I will be already equiped to change for the better the game I have paid for.
