Game fixes: Extended the OPH hack a bit to set APATH to each path in turn in addition. Should make the hack fix some Eurocom games (Sphinx and the Cursed Mummy, some Buffy thing, others?) 

VIF: changed a memcpy_aligned on 64-bit aligned data to memcpy_fast.  Doesn't matter with the current memcpy set we use but could have caused a crash in the future.
