I just made a Channel wad of the Duck Hunt homebrew game and installed with Wad Manager. IT WORKS! Now I can play it even without dependence on HBC or any SD CARD, cause it beccomes part of the System Menu! COOL huh!
Now just 2 more questions.
1) Where it said NAND Loader on CustomizeMii, I left the setting at the default "comex". Is that the best setting for converting homebrew games to System Channels? Or would "Waninkoko", the other option, have been a better choice?
2) Where it says Startup IOS, I left the setting at the default of "35" (that would be IOS35). My instinct was to leave this set as it was (and it seemed to work, cause the wad does work and so does the resulting installed channel) but would a different IOS have been potentially a better choice for converting homebrew games to System Channels?
