I've just bought a Japanese region wii u to play wii and wii u games, what homebrew should I install to play English games?

So as the title says, I've just picked up a cheap Japanese wii U so I can play all the wii and wii u games I've missed out on. Other than tiramisu, what else will I need? Ideally I'd also like to patch my wii u to an English language OS, but looking online the process for that seems pretty complex, although I've already got a few raspberry pis kicking about, so I could do it, if theres no good alternatives.
