No offence but it seems, you don't know much about homebrew, if you live in the uk, I can help you. I am offering DSiWare downgrade to 10.4 for £5, so I can get the game to do it. Once you're downgraded I will install A9LH for you, aswell so you can update to the latest version while keeping hbl(A.K.A Homebrew launcher, Also you can install any cia!)
