I recommend you to use pokégen instead of pokésav if you want to just generate a new pokemon from scratch. Pokésav comes in handy when editing certain things of your game savedata but has many problems with pokemon editing, thus why pokégen overshadows it...
pokégen is much easier to use and you'll be able to recreate this pokemon in a matter of minutes setting everywthing: shininess, EVs, IVs, item holding and even a valid PID (if you really want it)
once you created your pokemon with the pokegen, save it as a pkm file either for PC or party, then just load up your pokesav and load a party slot with the pkm file that pokegen just created.
you can find pokegen here: http://projectpokemon.org/forums/showthread.php?6424-Download-link-and-information
yeah I know this might not be the answer you're looking for, but trust me, the sooner you use pokegen, the better.
