So, I have a friend's o3DS with 11.2E firmware, I was using OoTHAX but now that soundhax came out I'm using that one instead, both work fine and I get into the homebrew launcher just fine. Now, I wanna downgrade this system, however I know I need one of those DSiWare exploitable games but Ninty has removed them from eShop here in Europe as well so I'm out of luck I think. I read that Sudoku's DSiWare version (the one from EA) also works and I saw countless guides and videos about it, however I just wanted to be sure. Did anyone try to downgrade their system with a copy of Sudoku? I don't wanna proceed to an unknown area without being sure I'm doing everything right. Yes I know Fasthax is coming out soon.
