I have more to add to my post. I went to the link and downloaded the "hack" file. I don't see a readme so not sure exactly how to use it. I did glance at the comments so maybe I missed how to do it. Do I just drop it into my SD card and run HBC? And when you suggested Priiloader, did you mean to install Priiloader and hacks.ini? Or were you saying either or? I have a 512mb SD card too. Not sure if size is important for a file this small.
Sorry, I guess I wasn't nearly specific enough.
1. You get the latest version of PriiLoader
here and put the apps folder from inside the ZIP in the root of your SD card and put the hacks.ini file in the SD:/apps/priiloader/ folder and then run the installer with the HBC to install it.
2. Once it's done installing and has sent you back out to the HBC turn off the Wii and hold down the "reset" button when you are turning it back on again. This will take you to PriiLoader instead of the system menu.
3. Go to the settings and make sure you have the option "use classic hacks.ini" set to ON and hit "save settings" and go back to the main PriiLoader menu (with the B button if I remember right.)
4. Go to "system menu hacks" and enable all the options you want. At least enable blocking disc updates and online updates but I would personally turn on everything that says region free as well. If enable anything else you think you might like. If it you don't like what it does you can always hold down the reset button the next time you turn it on and change them again.
