The PSP version of Champion Edition was released in 2006, as part of Capcom Classics Collection Reloaded. I believe the version on here is the same one used in Street Fighter Collection 2 for the Playstation, but (presumably) with better load times. You also get The World Warrior, Hyper Fighting and several other Capcom arcade games. Presently, this is the best version of Champion Edition for a portable console.
