Same issue here, BOTW gives the "The software was closed[...]" error message but every other game starts up just fine. I'm guessing the sigpatches are causing this?
I've been trying to install the patch but I can't get it to work. I followed every step in the OP and the game still turned up in japanese, so I tried to use someone else's patched files but same result. I can't see what I could be doing wrong, if anyone has any idea I'd appreciate it :(
Welp...
