Is there currently any MPO+ passwords for the original MPO characters like eva/ocelot/python/null? If there is could someone tell me them?

There aren't any. If you want those characters on MPO+, put in your original MPO UMD into the PSP. Imput the passwords for those characters so you get them on MPO. Save.

Pop MPO+ back in and it will say you have aquired new characters. They will then be in the rookies section.

There ya go.

Currently, there aren't any passwords for the American version of MPO+, only a few for the Japan version.
