my apologies for the wrong grammar, anyway, the website on the sticker of the r4i is www.ndsiLL.com, v.1.45, the flashcard is running on 1.42 help help
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
