Just got my Acekard2i's, that took a while.
(I didn't order it, but they gave me the Christmas version, which is exactly the same but in a festive box.)
I loaded AKAIO on them and they work fine! Much simpler and cleaner setup than my R4.
(Though not a fan of the spring loading, which I was glad R4 did away with.)
Of course moment of truth is when my friends try it on theirs.
Recently-manufactured Acekard 2i's will work on the latest menus for all consoles.
Ones made a month or two ago might not support the latest 3DS menu out of the box, but the DSi hasn't had an update in quite some time.
So basically, buying an Acekard 2i now will guarantee OOTB DSiXL support, and 3DS support after the Prince Caspian flash.
So if the cart reads as the Prince Caspian game, it should just work in a 3DS?
Thx
