I can confirm that DBI does not install updates and DLC sometimes. I installed Minecraft and then updated the file picked both games and updated hit install. I wish there was a way to install this sad it not been updated since 2022.
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
