ntr might even crash on o3ds but thsts not a smash bros related issue. it's an ntr stabilty issueSo it's not just an O3DS issue then? Well that's good I guess.
on o3ds ntr cfw stop because cakespatches are only for cake not for ntr so when it reboots... ta-da! it oes work on n3ds because there it doesn0t reboot.
