I was just about to say the same thing - why go through all the effort to patch the binaries when you can just redirect the DNS to your own server?

Then I saw something about signing with RSA - btw OP, the link doesn't work in your blog - there's some markup issues. But there's no discussion of where the RSA key comes from (just that you create one with OpenSSL). Does the Wii just accept any "signed" content? If so, wow, 2007 was a crazy time...

i thought the article was going to go there, just redirecting the host to a self-hosted ip address serving the bin, but i was pleasantly surprised it didn’t! interesting to learn about the patching process and tooling used
