it's possible since the saves are in psp's format, not some unique jpcsp one so they're compatible.
just copy the ms0 folder from your current version of jpcsp to the others and the save should appear in them too.
just in case though, you didn't turn the crypto mode on, right? if it's on you'll have to load the game, turn the option off and then save game to re-save it as decrypted. jpcsp can read decrypted stuff easily enough, but encryption's still wrong so older version could simply break with it.
