most wiiware can be regionfreed, but you need to patch the 01.app. As the wiiware have 01.app compresed you may find it easier to run the wads through wwpacker, you can find the tools on gbatemp by alpha0. Also this video patching method will work for many VC such as SNES and Genesis wads.
Hey, I'd just thought I'd mention another problem that alot of people around the interwebs are facing, and how to fix it. No-one ever resolved it, and it's annoyingly simple, at least in my case.
This appears everytime you try to run it in any kind of way:
Free the WADs *testing version* by Superken7
cannot open file freethewads
A few people mention they have been able to run it fine on other wads, same as me. The ones not working were set to Read-Only. To change, right click>properties on the wad file. And then uncheck the hopefully checked "Read-Only" box at the bottom of box in the general tab.
i cba to make an account in another forum, so hopefully sufferers will google the problem.
