I don't think psx games really need to be redump format as such, just use redump as a source to create single bin/cue (if they're multi bin). It saves people having to do it themselves.
no need to recreate the image as a single bin/cue, it will work in the emulator/buring program just fine and if it does not that program is garbage.
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.
