Owners of PS2, The Bouncer, and a DVD-ROM drive. Can you please help me? (Again, read why inside)

I see my last post was locked, you probably thought it was probably something to do with piracy maybe? I have no idea.
Why I need to know is because my disc is blue and silver and says 'Promo Disc - Not for resale' on it. I just want to know if its the same as the retail one, nothing devious.
Sorry if you have to lock this one as well, but I don't see why you had to do it to the first one.

It was probably a store demo or it was sent to some kind of videogame publication
for review.
