Update on the 3ds situation, and it's not a good one. I got a replacement SD card slot, but while trying to dissemble my 3ds, the right middle screw stripped, and is not not coming out.
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
