Thanks! Was going to play some DS games on the 3DS when I got time bombed, searched a little, thought that the only solution was set the time to 2010, which was going to mess with Animal Crossing, then I finally discovered this, really saved me...
I got an R4i 3DS RTS, great card, with awful stock firmware. It wouldn't load Mario Kart DS for Kanri's sake. But this makes it not only actually usable, but enjoyable and easy to use. Greatly appreciated.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
