Old school platformers for PSone?

I accidentally bought a PSone today, and I though that it may be a good present for my mother on her birthday, but I must know; are there any really good old school platforming games on this console. I mean an par with SMW, Yoshi island and so on? And, another question, is Mickeys Wild Adventure a good game, because I accidentally bought that too.

No PS1 platforming game can match SMW or Yoshi's Island.  In fact, none come even close.  You will want to try games like Skullmonkeys and maybe Tomba, but they are not in the same league.  Castlevania:SOTN is in the same league, but not a platformer per se.
