Okay, I'm kinda curious about this.
Finally was able to get things sorted with Best Buy regarding the snafu's with my DS lite. Now came home with a fresh new 3DS.
Before this, I had ran that firmware update for the Acekard 2i (mine's HWID is 44), and everything according to it went successfully. 3DS booted up with firmware 1.0.0.0U.
The SCDS2 has also been updated, and shows up perfectly fine on the 3DS; loads up and everything. Plug in my acekard, it actually shows up AS an Acekard 2i in the 3DS's main menu. But when I try to load it, I then get the "an error has occured" dialog on the bottom screen, and have to turn off the 3DS console.
So, what's the dealio? Should I (re)flash the Acekard with my 3DS? Or simply update to 2.0.0.2 now?
