It was more about the quality.I wrote a nsp builder, I think that's a fact right now, but as I've ALWAYS said it's AN ILLEGAL tool
I am not gonna lie, thats wrong.Let me just explain the steps you went through.
You took one of the illegal NSP files, used hactool to extract it, and used Xor's tool to replace stuff in the logo partition with nothing.
You hit build and said it was "legal" because you assume the tool is its own thing that doesn't use the SDK, however it does have the SDK inside of it.
