Healthhii is an application for your PC which allows you to replace the health and safety warning with a picture of your choice. This is only compatible with 3.2U and 3.2E currently. Also, you need to have a Windows PC.
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
