Help with Ps1 Games That Play on the Ps3 Please?

I used to have a Playstation 1 but sold it, then got a PS2 and sold that and now I have a PS3. I loved the 'Spyro The Dragon' series on the PS1 and I really want to play them again on the PS3 but the only game I can find is 'Dawn of the Dragon' but I want the originals like 'Spyro The Dragon' and 'Year of the Dragon' but I'm not sure if they'll play. I was wondering if anyone could tell me which Spyro games out of the entire series will play on my Playstation 3? Thanks!

Suggestion:

No ALL Ps1 games will play on ANY Ps3 no matter what model etc even the slim will play them

If you have a 60GB PS3 then you can play ALL Ps1 and Ps2 PS3 games

The 60GB PS3 is the only ps3 that will play ps2 games but all ps3 play ps1 games.

You can also buy ps1 games from the ps store for £3 to £8 as well as gamestation and cex sell them for 50p to £5
