The PS2 version is defective. Several vital controls stop responding about 30 minutes into game play. Of the two dragons (Spyro and Cynder), both are supposed to be able to go up in level, but the control needed to bring up Cynder (L2) does not work. Tried every possible button in case manual was wrong, to no avail. The control to switch between Cynder and Spyro in single-person mode stops working after the opening scene. In two-person mode, Cynder's magical attacks stop working after you lower the horn to the floor. Because of these broken controls, we became permanently stuck at "blow horn to open door" about 45 minutes into the game. Played through several different ways, and nothing helped -- not even the Cheats listed on internet sites.
We have a new PS2 station, and we bought a new copy of this game. This isn't like a PC game where there is some hope of a driver update to fix the problem, either. Only buy this game if you can find somewhere that will accept a return for cash or a different game entirely (NOT a new copy of this one).
