Wii u of course supports any kind of scripting
it just has to either run with a compiler (when the code is read) to send information to the OS, or be compiled code for the machine to interpret.
Also
iOS ~= OSX ~= OS ~= Linux OS
I AGREE! WE NEED ROBLOX FOR THE WII U! All I have is an XBox360 and a Wii U for consoles. I am not willing to get an XBOX One (S) in order to play Roblox. Granted, the Nintendo Switch came out a while ago, but why not put it for the Wii U?
