Hi there, I've recently got a japanese wii u for modding purposes but as you saw in the title it's having some problems. The thing when i plugged it on everything worked great until i tried to begin with the homebrew process and the internet browser would not work. It displayed the error code...
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
