Recently, it has become increasingly hard to get things to work. I've made very little changes to my 3DS XL once I set it all up to work correctly, so why this is happening suddenly is a mystery to me, the three main issues I'm experiencing are the following - 1: When starting my 3DS XL, A popup informs me that my SD card is write-protected, even though its not. I have to restart several times & re-insert the card to fix this. The card is a name brand SanDisk Ultra 128GB MicroSD card purchased directly from Amazon. I use the provided SanDisk adapter to use the microSD card in the SD card slot. 2: When booting Gateway mode, I'm often presented with yet another message saying that my Gateway card is not detected. I have to re-insert & restart my 3DS XL multiple times to finally boot into Gateway mode. 3: Finally, when in Gateway mode & attempting to access the game selection menu by pressing select, I get yet another error saying no MicroSD card detected in my Gateway cart resulting in the failure of loading my games list. The MicroSD card used in my Gateway card is yet another SanDisk Ultra 128GB MicroSD card purchased directly from Amazon. Does anyone have any experience with any of the issues I have outlined in this post? Any fixes I can attempt to reduce ANY of these problems? I've tested my cards on my desktop Windows PC & ran various diagnostics on them, but found no errors. They can be read perfectly fine, every time, using my PC. tl;dr - Im constantly running into issues where my Gateway card, SD card, & microSD within my Gateway card cannot be read or falsely report that they are write-protected. Any advice is appreciated.
