    Code:
    Note: this is not a backup loader, in any way, shape, or form. If you’re looking for a backup loader, please move along.

While Nintendo did reply to bushing’s open letter, he has not succeeded in establishing a conversation with an engineer about the issue. Furthermore, we have learned that they received and read at least two of the original three e-mails that were sent prior to the open letter, and decided not to reply (in fact, one of their replies was to one of the original e-mails, but only after the open letter was posted). Therefore, we can only conclude that they are not very interested in the issue.

As many of you may already know or have deduced, the bug in our open letter referred to a way of reading DVD-Rs (and Video DVDs) without the use of a modchip. Several people have investigated the bug independently, and they’ve gotten pretty close. However, we did discover an easier way of enabling this mode from homebrew, which, among other things, does not require any changes to IOS at all. This method is also relatively difficult to transform into some sort of backup loader.

Erant has been developing a library that uses this trick to enable DVD access for homebrew. We hope to release it this coming week, after a few details have been polished. svpe and dhewg have been working on a native mplayer port that uses this library to play back DVDs, which we hope to release as a proof-of-concept together with the library. We also have DVD-loading versions of snes9x and Genplus.

Non-modchip users will not need a custom IOS. Ironically, this method doesn’t work for users of some modchips. Therefore, these users will require a patched IOS using the well-known UnencryptedRead patch (the library will automatically use it if needed). We’ll try to release a somewhat more user-friendly version of patchmii dedicated to this task together with the library.

    Well....

    I'm guessing in 3 days there will be a Custom Firmware that will play copies on unmodified systems...it's only a matter of time now
    Harshboy: it's not that easy.
    I'm willing to bet it'll take more than 3 days.

    I know I'm going to get flamed for speculating this (because apparently if you don't know how to code you're not allowed to speculate), but I know there is a game loading code that can be run from homebrew (because Squid was in IRC talking about it with his Wiimu development). I don't know alot about it, but couldn't you put 2 and 2 together and make a DVD backup loader?

    Maybe not by the guys over @ Hackmii,but if its possible it will be done you can be assured of that,anyway it will be quite handy for playing roms of a dvd but rather pointless as a dvd player imo,although I understand its just a p.o.c.

    i am guessing you mean the gecko os as the loader with the dvd access

    well it might work if the source of gecko os was to be released but the maker isnt a big fan of piracy

    this is really something I never expected to see happen, awesome


    about using it for piracy, as he said, this would require a fairly good & experimented IOS hacker, see if this one really exist now without twiizer help [​IMG]

    Well, at least we'll get homebrew DVD loading, I was sure that it wouldn't be possible as long as they were determined to inform Nintendo on the recent exploit they discovered.

    i dont think geckoOS could be used for sorce to an ISO loader, everything is done on the wii hardware not the app its self

    Awesome news. Now I can play DVDs in my room. About the ISO Loader, so it means its possible but it'll need some experienced to make it?

    it won't help since the game still makes his own access to the dvd, and obviously can not use this "lib"

    I imagine that Gekko RF only patch some part of the RAM related to dvd region & video mode then launch the main dol and leave the game alone

    What gets me is where they draw the line:

    So, emulators (piracy) for older consoles is acceptable, but anything that licits a loss in market share isn't?

    I wonder how they feel about releasing a GameCube ISO Loader....

    That seems okay as of course no one still buys gc games.
