I decided to start playing Secret of Evermore yesterday, proving to be interesting so far.
Ya should check Romhacking.net for some nifty enhancement hacks for it, like a balancing patch or 2 player mode.
Evermore is indeed a SNES classic.
THE BEST METHOD to run PSX games (and everything else for that matter) is via Retroarch - http://buildbot.libretro.com/nightly/
If you have any questions on how to set it up on Windows please feel free to ask, its very easy.
