I dropped out of the flashcart game years ago. I currently have an AK2 and an iTouchDS and my old DSLite friend. I show up here to find out what firmware I should be running, and there's this fancy AKAIO out there, and now I'm lost. AK is open source? I didn't remember that ... In short, is that the firmware I should get loaded on my AK2 for maximum compatibility/performance?
