i dont know about WORKING code, but if you use the full party code you can use riku that way but he crashes on certain worlds i believe
i have no idea tbh i used both at once, wisdom sora, t-stanced alot, you became valor sora and normal sora at same time, by controlling both, well you control all 3 but wisdom t-stanced, and you can go to menu with them and you get 3 soras looks funny. i went to hall of cornorstone to test them since it was a open area, and could see better. try again. maybe it just crashed for you.
otherwise i dont know pal sorry.
just tested them, (yes i work that fast) they all work and i thank you cos they made me happy, the tifa and yuffie codes the best. great seeing the girls take on sephiroth, reminds me of FFVII AC.
