I tried that but could not work out what the previous version, before 2.0, that I had was. I tried a few different wads to uninstall and they all made no difference. I also uninstalled the 2.0 channel and delected the config folder. I then reinstalled 2.0 channel and still cannot play more than 10 minutes of NSMB. All other games that I have work.
I also have it has an app, version 1057 via homebrew channel, and I have no issues playing NSMB. The reason I nee dthe channel is my son plays the game, who is 5, and I dont want him playign around in the HomeBrew channel.
Any help would be appreciated.
