"A note to users and distributors:
It has come to our attention that HDLoader has been counterfeited by a company in Hong Kong and is being passed off as original. Any company who purchases and then distributes such copies will be the subject of immediate legal action without the opportunity to simply desist selling. We have a zero tolerance policy on this issue. We regularly make samples purchases from all distributors. Those selling any counterfeits will be contacted by our lawyers without hesitation.
HDLoader will offer an upgrade service in the future whereby users can obtain a newer version by returning HDLoader together with a handling fee to us. We will not offer such service on counterfeit discs, be warned!
If you have purchased a fake copy of HDLoader, we advise you to seek a refund from your vendor and purchase a legitimate copy from one of the official distributors listed below so that you are eligible for the update service mentioned above."
Maybe it´s Sony, maybe not... there are other ways to get it...
