I was wondering if i can still hack my Wii after Nintendo shut down some things, not sure what they are but had to do with messages and stuff. Can I still install the homebrew channel and other third-party software?
Homebrew channel still works well, and this process should be fine if you're completely up-to-date:
All it requires is an SD card. Good luck!
This all depends on your system version. Version 4.3 may still be hackable, but each version may have specific ways of doing so. For more information, go here: http://www.wiihacks.com/recommended-faqs-guides-tutorials-only/96886-guide-softmod-any-wii.html
