The are used and all did work when I played them last but that's over 20 years ago.

1:  Tekken 2 1996.

2:  Destruction Derby - 1995

3:  Power Soccer - 1995

4:  Grand Theft Auto (GTA) 2 - 1999

5: Tomb Raider - 1996

6:  Wipeout - 1995

7:  Spec Ops 'Ranger Elite' - 2000

8:  Pac Man World - 1999

9:  Viewpoint (disc bit damaged) - 1995

They all have the booklets in good condition only the Tomb Raider booklet sticks a bit together.

Tekken 2 has got a bonus demo disc included and there's also a separate single demo disc included from 1996.
