I'm trying to play SNES with dock but cannot fill the whole screen how can I change it to stretch I tried turning off square pixels which helped a little bit

If anybody here speaks japanese can help me install the language keyboard for fcitx5-mozc I dont know the proper way to install it thank you.

I heard new OS come prepackaged with Shelly so what if I already have cachy os installed will it be pushed into my machine?
