Really sorry. When I tried using pkNX with 1.2.1 and it didn't work for me, but that's the same with 1.2.0 as I never got it to work until now. Thank you for your response, had you not I probably would have waited for another pkNX patch.
Yes. It took me a day to figure out how to install atmosphere, tinfoil, and get the patches for my fw, but pkNX is finally running on my Shield game.
