hm i have the same problem
Xavier do you solved the problem? i haven't cubic ninja so i can't use this plugin. i have only a gateway 3ds on 3.2.1 i haven't installed any updates. i used the patcher for pokemon y. i think im to dump for it. does anyone tested it on his gateway and works fine?
update: now i downloaded the update 1.5 and the rom start. can i play this hack with the update? i don't think so or?
update 2: after deleting the update the rom doesn't work. when i start the rom the game crashes
