So I just got this card in the mail myself, ordered it from nds-card (
https://nds-card.com/ProShow.asp?PageNo=2&ProID=575) but whenever I try to launch it in regular mode (to play NDS games) it either stays on a white screen or gives an error " "
I have a 16 GB Toshiba FAT32 microSD card inside that worked perfectly fine with my older R4i 3DS RTS (see picture below). I tried to put the Wood firmware on it again but to no avail. The microSD card still works just fine with the old R4 so that's not the problem anyway.
Furthermore the new flashcard also works does NOT work on my classic NDS Lite.
I have confirmed that it is switched to the "D" mode.
Can anyone assist me with this issue?
