Thanks for the reply.
My box is the A5 sized one, and contains only the quick key control guide, a firebird registration and a firebird sticker.. thats all.
I will be getting back to the seller ASAP regarding this. Unfortunately it was not paid via payPal, so there is no insurance, but the game cost me $61AUD.. and claimed to be complete.. so I am not pleased.
Before winning the auction, I searched high and low regarding contents of the box and found no information on the net, other than a few box pictures.
I have the C64 version of this, so I did expect a little more documentation, but since I could find no evidence of any contents, I took the seller at their word.
