It also didn't work on AKAIO 1.6. I've already tried formatting my SD card but that doesn't work either. At first I just ignored it but after a while it got pretty annoying loading the Acekard again every time I want to play a different game.
E3 is going on June 15-17. G4TV will be broadcasting E3, but Youtube and IGN will also be streaming it. Not sure who's going to be giving a presentation at what time and day though.
I'm going to format my 8 GB Kingston SDHC card for my Acekard 2i, but seeing how I'm on a mac, I can't use the Panasonic formatter. But what I can do is format it in Disk Utility. I'm only worried it's not going to format it properly and cause problems for my on my Acekard later on.
It depends what your preferences are. I have a DSi and love it, but I have also used an XL before. I personally didn't like the XL as much as the DSi since it just felt too large for me, and not portable enough.
