discovered that if some Japanese or europe games are injected into the American Wiiu the screen goes black and the game does not work, but if you change the region of the Vwii, dumping its setting.txt via ftp and using settingEdit, and changing the language to JP and the region to JPN, save and replace these files there on the vwii's nand, the games that stay on a black screen, will work however, you won't be able to play some injected American games, in short it's better not to do that.
I hope some dev reads what I'm going to say because it will help the Wii U community, there has to be the possibility of creating an aroma plugin, or patcher that makes injects or games on the Wii disc become region free when using it. them in the Wii U menu, this would solve the problem because if you had something that emulates this setting.txt and detects each game region the games opened, why would they be in the correct way that each game runs, would solve the problem, and so every Wii injects game region would work on any Wii without needing to modify the Vwii's setting.txt to run some games and return to normal to run others, that's the idea friends.
small game examples to nothing work on WIIU versions:
Tales of graces - work only WII U JPN ( USA/EUR nothing )
Bomberman blast japan - work only wiiu USA/JPN ( EUR nothing )
Naruto gekitou ninja taisen sp - work only WII U USA/JPN ( EUR nothing )
solution to the problem is to have some plugin or patch that automatically detects the region and video output along with the language, just like the region free plugin on the Wiiu would need one for the Vwii.
