I've been playing HM way too much time for a break.
Think of it this way, too much time playing Harvest Moon or farmville?
Ya never too much time playing Harvest Mon.
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.
