Not sure if this one should go here or in the 3DS section, but, considering that the problem is with NDS games, I decided I would aks here first.
A little bit of history: bought a R4i Gold Plus (the one with NTRBoot switch inside) for my New 2DS XL in August of 2017 for DS homebrew development...
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
