I have had my DSi for a couple of years. According to system settings it's 1.4E. I've never updated it since I bought it. All I use my DSi for is games, and 99% of the time they're played from my DSTWO (I also own an Acekard2i but never really use it, the DSTWO is just better.). Is there any reason I should ever need to upgrade it? As far as I can tell, it'd offer me nothing and potentially cause my DSTWO to stop working? I just can't see any reason I'd ever need to. I guess I can't understand: why do people care about flashcarts working on the latest version so much?
