It is not a question of homebrew or CFW access on the console. The Wii U drive itself doesn't read standard DVDs.is there any app like that so i could burn a rom to a disc?
Even the last Wii drives didn't get modchips. There was some announcement for a "WiiKey U" but as far as I know it turned out to be vaporware and supposed to be an optical drive emulator. No idea if it would have been able to patch the drive for reading standard DVDs and BDs.Nope. The drive is completely different in the Wii U from the original Wii. It would require a drivechip (none were ever developed for the U).
Honestly, USB loading is the way to go. Its much faster than the disc drive anyways. Check this thread here for everything you need to know for setting up homebrew, USB backup loaders etc https://gbatemp.net/threads/the-definitive-vwii-hacking-guide.425852/
Neogamma can even throw some "drive too new" error if I remember that correctly.I think even the Wii couldn't run burned disc anymore on latest revisions, something with drives not being compatible anymore with the DVD norm. (but I might be wrong here, it's been too long)
