So I haven't booted up my DSi in a long time, but my friend is wanting to play Pokemon Black & White 2. Right now my DSi is on 1.4U. So I have a couple questions: 1) On the download page of the Acekard site, it mentions it has a firmware update for the DSi 1.4.4. How do I update my system from 1.4 to 1.4.4 if the latest out there is 1.4.5? Like, how do I choose for my DSi only to update to 1.4.4? 2) Does that firmware work on the DSi 1.4.5? 3) It looks like AKAIO 1.9.0 is the latest. I'm assuming this plays Pokemon B&W 2 fine? 4) Do I need to even do any updating to play B&W or should it work on my 1.4U DSi? Any assistance would be great. Thanks.
