Just got the M3i, all happy and stuff, and immediately flashed it with the already prepared 1 GB Micro-SD card I had, waiting a full minute after the flashing stopped, and popped it into my DSi, and click the icon as it appeared. Then it hit's me. "An error has occurred. Press and hold the Power Button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting." Now, I thought maybe I flashed it wrong, so I tried several more times, before just giving up and putting it in the DS Lite, works great. So, is there possibly some reason why it just won't work with the DSi? My DSi is apparently version 1.3U.
