Hi everybody! I'm a novice at this but I just got an ak2 and I kinda don't understand what the difference is between the firmwares AKAIO, Bliss and the official firmware??? Which one is better and why? I'm only interested in backing up my roms on the AK2 and I really don't care about cheats cuz I know I can beat any games without them which is much more fun to me! Thank you for helping!
