The question on the topic title expresses my doubt. Also, what exactly does the AKAIO firmware do that the official DSi firmware doesn't? Also, does it have a better battery life than a CycloDS with the battery saver? (If compared to a DS Lite since CycloDS Evo is still not DSi compatible) I'm asking since I have a Cyclo for my DS Lite and I'm worried as the DSi has a worse battery life than the lite. Also, please answer my question in the topic title. I'm buying the DSi once it is released in the US. Thanks in advance.
