Here's the thing: my friend has two AK2s running Pokemon Diamond and Pearl respectively. Everything's running fine, and he's perfectly able to connect the two via wireless .. when he trades Pokemon or exchanges data however, everything works fine until the games try to save; then they give blue "A connection error has occured" screens, kicking him back into offline part of the game. The sound stutters during this, probably because of the amount of data written .. could this be the culprit? He uses two AK2.1s, with fresh Taiwanese Kingston cards, so the hardware should be fine. Both were running AKAIO 1.2, and I had him update one to AKAIO1.3b2, but that seemingly made no difference. No cheats are active.
