For anyone interested (I havent used this yet but a few posts claim it works) and i just downloaded it now, google : "Free the wads" - allegedly makes wads region free ;-)
I will report back if i get a wad that doesnt work to run....
OK first game i tried - Family Table Tennis wad or something did NOT work - loaded then on start gave black screen......BUT...
Eureka! Midnight Pool which did NOT work originally, DID work after using "Free The Wads"
Either the Table Tennis game was a dud download (unlikely as it did appear as an animated channel and allow pressing of the start button)or as with other apps its trial and error/ hit and miss.
Having the exact same problem with a lot of download content (DLC) wads. They install with wadmanager 1.4 just fine. Channel shows up fine too after they're installed. However, when I load the channel, it's just a black screen and the wii remote is unresponsive. After that all I can do is hard reset the console.
Some DLC wads work, but most don't. Is this because the wad's are bad or what? I'm running a 4.1u softmodded wii with cIOS38_rev13a and wadmanager 1.4 for the installs. Wads were obtained from wii****wii.
I also made sure to run them all through "freethewads" to change them to region 1 "NTSC 4.1u" and have all of the preloader region hacks enabled too so I'm pretty sure it's not a region issue.
