Hi, I have a 64gb Sandisk SD card (exFAT) which I used for 3ds roms on my New 3ds XL - Using Gateway. It works perfectly. I bought a new 128gb Samsung evo SD card and I tried copying all of my 3dz files from the 64gb sd to the 128gb sd (both exFAT) but when I try to launch games from gateway on my 3ds Only a few appear w/ the image icon and the rest appear blank. I tried to point Gateway Rom Patcher v1.1 to one of the Roms on the 128GB and it said invalid ROM. I remembered that when I modified the header on the 3ds roms and changed them to the 3dz format it detected the chip ID (sandisk SD) and it made a few changes. I assumed that I needed to do this as well with the Samsung card. So i grabbed again a fresh rom from my PC and when trying to use "auto-detect" chip ID on the gateway rom patcher it says. "New Chip ID Generated. Manufacturer can't be verified, and it still shows the manufacturer as SanDisk I try to choose from the dropdown but Samsung is not listed. Is there a process that I am missing here? Thank you in advance for the help.
