Most current CFWs have region free, but you'd need a gamepad to run them directly from browserhax, or install a CFW
You could change the game region over ftpiiu-everywhere, but (unless you already have haxchi/cbhc + wiimote + hbl channel) you'd need a gamepad to get into that homebrew
You could use System Config Tool to change the game region, which can be used with a pro controller, but unless you already have it, you need access to homebrew to run wupinstaller
