It looks like the Acekard 2i may not work on the new DSi XL model. I just returned from Gamestation where my brother works, and we tested my Acekard 2i on the new system. At first, the icon would not appear on the DSi XL menu. A quick re-insert brought the icon up, but trying to load "Danny Phantom" results in an error. I also checked the firmware, it's 1.4E. So, there you have it, it's possible AK2i doesn't work with the DSi XL right now. Just thought I'd share my anecdote, who knows, it might differ from person to person.
