Dragon Quest V(U) help pls

Hi :), i got a question. How come when i download the (U) rom on the site but the language is not english? and how do i fix it?
ty if anyone could help me pls^^

(u) means north american region. this could mean english, french or potentially spanish depending on the rom. if you are using a flashcart, make sure your DS is set to english and your flashcart firmware is the english version.

oic thanks loonylion^^
