I see ! Thank you very much guys. I will try right now, I just installed for the first time a game witj wup installer and the differenxe with loadiine is amazing. I don't have a big isb hardrive right now so that's why I was thinking about nand install, but I will try to inject a ds game in the usb stick now then. It's amazing how you can launch game so easily after you installed them. Thank you so mich guys.
