Thanks for the responses. I came across another game on the weekend that said it included demos, I'm guessing the sticker on the game box was some kind of promotional item that was handed out at purchase and not packaged with the game considering the case type can only hold one disc.

Formula 1 97 - Free radical demo (various psygnosis games including g-police)

The List so far...

Ridge Racer Type 4 - Ridge Racer Hi-Spec Demo
Klonoa - Point Blank Demo
Final Fantasy 7 (platinum) - FF8 movie demo
Vandal Hearts II - Suikoden II demo
Resident Evil Directors cut - Resident evil 2 demo
Final Fantasy 6 - Final Fantasy 10 (PS2) demo
Tekken 2 (Platinum) - Point blank demo

Needing confirmation
Soul Blade - ?
Crash Bandicoot - ?
