That's quite a haul there...I'd be interesting to see how much BMX XXX is changed from the release version if at all.
Well as far as that goes its gunna be some time before I can give you any hints. Finding a spare NR reader is no easy task. Finding a spare debug unit for ANY modern system is tough. I did manage to land an Xbox dubug unit on ebay recently though.
