I presume Acekard can only play BIS through AKAIO?
I base this on the fact that recently, don't know what struck me, but I decided to replace AKAIO on my Acekard 2 with the official Acekard firmware just for the heck of it, and to see how it would work.
Some of my games could not even start, including Bowser's Inside Story.
So I thought f**k it, it's true what they say that the original firmware is worthless.
EDIT: Ooops, I see the question was about Acekard 2i, I was talking about the "standard" Acekard 2.
