How I can change menu background, the part that say "Brawl, Solo, WiFi, etc"?
It's all in the mu_menumain.pac file :)
Nope, I found out that I just put the file in menu2 and rename with _en at the end
What file? Anyways the file(s) you're talking about are probably part of the mu_menumain.pac anyway, because it goes in pfmenu2
