okay i have a 3ds that's on 10.7 firmware and a copy oot3d.But i can't download the payload for it using oot3dhaxx instller because my freind has menuhaxx and can install it from that oot3d haxx installer. so would it be possible to put on a "otherapp" payload file on the sd card as well as the boot.3dsx file on the sd card or th haxx to start up? or does the payload need to be on the game cartridge?
