You don't need the official to run AKAIO but if you still want to use it, AKAIO allow you to do that.
Just put the official's "akmenu4.nds" file in the _aio/ak2loader folder (rename it like you want. ex: Official.nds)
That way you can choose between Official and AKAIO in the rom properties (Y twice at the rom selection screen)
Keep in mind that if choose official, the soft reset combination will be L+R+A+B+X+Y instead of L+R+A+B+down.
