I just did the update (from v12 to v14), big problem, it's like the update didn't work and worst, i got this message : I have a DSi with firmware 1.4U, a EZFLASHVi (who was v12  and with the crashes and slowdowns). I have a Sandisk 2GB microSD, cluster is 32kb. I can see the Tak image game. Okay,so far I tried the EzFlash with my big old one DS (not lite), it works like a charm owing to the v14. Because with v12, I did get the slowdowns and crashes. I tried playing : _ Zelda Phantom Hourglass Good _ Jump ultimate super star Good _ Soma bringer Good _ Devil Survivor Good Sorry if I don't understand some things, i am pretty new on this, I bought my cart on March 2009. Thank you for your help, I really appreciate it.
