atually i was testing cod mw3, the cod that was release after black ops 1
but i remember they both had the same issue of freezing at begining until 257 or something was installed its been so long i forgot the exact name but both of them needed before i started using dx2 v6
dx2 v10 vwii played cod mw3, to be perfectly honest i did not test black ops 1
my black ops 1 and mw3 are both NTSC
