I'm having the same issue. I have a new 3DS XL purchased the end of November 2014. I first had a red-button Sky3DS, which I've exchanged for a blue-button Sky3DS, both give the same "the Game Card was Removed" error. I have exchanged numerous emails with the Sky3DS team and have not come to a solution. I'm hoping to find anyone who has found a fix, or the root problem. Here's the steps I've taken:
- As stated, replaced the Sky3D card itself
- Tried the following brands and sizes of microsd cards:
-- Sandisk 32GB
-- Sandisk 64GB
-- PNY 4GB
-- Kingston 8GB
-- Kingston 2GB
- Tried several USB and SD Card adapters
- I've tried two windows laptops (Windows 7 and Windows 8). Virtual windows running Windows 7, a fresh clean install, using Parallels. A boot camp, fresh install, of Windows 7.
- Used diskWriter versions: 1.00, 1.04, 1.05, (and the oddly named 1.07, which is older than 1.05)
- I've used their respective template files in various combinations
- I've formatted and reformatted using the several different versions with all the cards listed above, using verify on the newer version of DiskWriter
- Downloaded several different copies of the same ROMs, using the exact same 10 games as a test bed.
So far, I've not had one game run successfully, even once. I suspect that Nintendo has some detection in the newest hardware that Sky3DS hasn't compensated for in the code.
Any help is appreciated.
