Play as Serge (Help with Gameshark code/Character Modifier.) Spoilers

[legaiaflame]

Trying to get this gameshark code to work to play as Serge after you swap bodies with Lynx:

Alternate Character 1 Modifier
D00DAF18 0001
300DB0A5 00??

Does anyone know what two digits to put here to play as Serge? Tried 01 and human Serge shows up but if you use any special moves the game freezes.
