Recently I saw a video about a GBA SP cartridge swapper thing where you could insert 3 cartridges at the same time and use a little switch to swap between them. My initial response was why doesn't something like this exist for the switch so that docked mode players can just swap between games...
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
