Hi Alan,
Not sure exactly what an opos card is, or where to get one, maybe Ebay
However all the rumours are that this file is not a fake and the real deal, also the readme file that come with the OPOS files say's the following
' Hey guys,
today we release a new file for Sky and D+
This is just a S2 File. Xin1 wil follow early this week
For support visit

Soooooooo it looks like files for most of the cards will be available soon, maybe even the KNOT O-Ha
Should be a lovely Xmas .............
Cheers
AJ
