    GCOS V4 Final

    DVD9 support, ISO generation speed








    [​IMG]



    GCOS V4 Final has been released which includes the long anticipated DVD9 support. Emu_kidid's popular GameCube Operating System now allows for multi-disc games to stored on DVD9 discs that provide a huge leap in file space.






    [title:readme]*Do not use Shrunk Audio streaming games (they may crash!)

    *Memcards may have an issue.. i.e. save a game from a dvd9 disc and then it won't work on the game if played by itself.. (?)



    Notes:



    Using the app:

    You must specify a region for the output file.

    Examples are:

    GCOS MultiGame Creator V4.exe output.gcm USA game1.gcm game2.gcm etc

    GCOS MultiGame Creator V4.exe output.gcm JAP game1.gcm game2.gcm etc

    GCOS MultiGame Creator V4.exe output.gcm PAL game1.gcm game2.gcm etc



    It will create a self-booting GCOS dvd



    After a bit of tinkering, GC MultiGames are now working fine on GCOS [​IMG] Use our own little application to create GCOS GC MultiGame DVD's up to ~8GB (full DVD9 size to be exact). That's right, GCOS has it first! You may pre-shrink Isos first using GCM Utility 0.5 (one by one).



    Takes about 8min give or take to create a ~8.3Gb Iso image on a 2.4Ghz P4.



    Why is Cobra MultiGame DVD support only "partial"?

    Since Cobra MultiGame DVD's rely on games being on 32kb aligned, some are not playable as this changed now to 128kb. This means that most likely the first title burned on the disc won't work. However instead of removing all support for them, I have left in partial support. GCOS will scan your disc, find whatever it knows will work on Wii drives and only list that. However if you run the DOL file provided on a GC, you will have support for old and new.



    Technical Notes:

    If you want to develop your own app to make these multigame dvd's, here's a rundown of the disc format we made:

    -=The GCOS MultiGame DVD Format=-:

    Header: Just rip the header that a game makes, easiest way to explain.

    Offset table is at 0x40, same as CobraMultigame (in DVD9, offsets are >>2).

    First possible location a game can be is at 0x20000.

    All games must be placed on offsets divisible by 0x20000 with no remainder. (Aligned)



    Thanks to dernettemann1983 for the news tip!

    It is? I've never heard of a retail Wii game using DVD9 yet. It's too bad Wii games aren't certified by the DVD Forum.

    Woah. That's pretty impressive. Although I couldn't stoop to the low level of using full-sized discs for GameCube games.

    Work what? Learn English.

    Is no one paying attention?

    This is to run a DVD9 disc filled with GameCube games on the Wii.
    I suppose you could also fill it with more roms for emulators (snes, etc).

    no, the laser didn't move that far. it could only read the smaller DVDs (8 cm?), or the same area of a larger one (12 cm?). the Panasonic Q could read full sized DVDs, but not in GC mode, only DVD-Video mode.

    cool, i'm gonna use this to boot my action replays and freeloaders e.t.c.

    edit: i tried to make a bootable disc with the bootable disc3 package i've got but the the iso was not the correct size, is there any way else to compile a iso to burn?, and no i'm not interested in making a multi games iso i just want gcos to boot my action replay and freeloaders so i want to make a simple iso.

    Hmm it doesn't seem to work when I try to use it on my Gamecube via my Max Drive :\

    Is this for use only on the Wii?

    I didn't think it was considering it says in the OP under whats new the following...

    ** FINAL v4 Release **
    - Gamecube Supported (Softmod and XenoGC)

    I think he wants to know how to make an iso for a single game instead of one that outputs a multi game iso [​IMG]

    Why bother using GCOS for a single game then? Why not just burn the game by itself?
