The are genuine in that they are made from the same factory/parts that the official pads were made from. The only difference is that these are not approved by SEGA.
There were a few threads about these at shoryuken.com. Someone even took pics of the circuit board and it is identical to the official ones.
They are legit. I ordered one around Christmas and it is just like my two Saturn controllers. It is a great controller for emulators and can even be used on a PS3; only for PS1 and PS3 games though as PS2 games require the PS button. They're a great and cheap alternative for SFIV; too bad I already have a pair of Hori RAPs modded with Sanwa buttons and button plugs.
They're legit, Sega made them, and they even made a white version. They were made a few years ago, around the same time as the Saturn PS2 pads.
What about those controller converters that let you use a PS2 pad on a PS3? How do those work?

I have a pair of converters (can't remember which brand off the top of my head), but they work like a charm with my PS2 Hori RAPs. There is no lag what so ever and they even work with Guitar Hero if that's your kind of game; most converters struggle with GH.
No, they don't work on a 360. The 360 doesn't pick up the required USB drivers like the PS3 does.
