It is in save manager gx format, I'll eventually get it into the save format dolphin also uses. As a personal request do not use this save online. If you can change the name of the save some way then I would be ok if you went online with it.
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
