Ok, so I finally got my Acekard2 today, and just for the heck of it I tried using AKAIO 1.5.1. Unfortunently and much to my dismay........ Nothing wen't wrong! All of my saves remain intact, nothing freezes at all, everything works perfectly. I've tested it with my own backups of Pokemon Pearl, New Super Mario Bros, and a slew of other games as well, including Spirit Tracks, and nothing has gone wrong. Btw, the PCB or the area around the contacts is a very dark green color, if that indicates anything. Other than that it's been less than 2 hours since I unpacked it, and I am just loving this thing like crazy. This thing is... FREAKING AWESOME!
