    I want to play GCN games off of my external HDD, but what format do they have to be in to work properly.

    The easiest, you can just take the original ISO or GCM file (A GCM is just an ISO with a different name) and change the name to exactly "game.iso"
    for example, mario.iso would become game.iso
    put it in a folder with whatever name you want and put THAT folder in a folder called "games" on your Wii HDD so it would end up looking like
    /games/blahblah/game.iso
    with no change in format whatsoever. (this is also known as RAW format). This is usually the most compatible format, too.
    If you have a game with two disks you would save the disk image for the second disk as disc2.iso

    If you want to save some space you can use a "trimmed" ISO image. (Game disks often have a lot of "padding" which is garbage info that's just added before the real info so that the real info ends up closer to the edge of the disk where read times are faster but in a disk image on a HDD that has no real use.)
    There are a number of tools that will do this for you but the most common ones lately seem to be DiscEX, GCIT, and DMToolbox (which actually comes with the DM(L) download).

    The other option as far as format goes is called FST format which is basically just all the files on the game disk extracted out into a folder. This is commonly referred to as GCReEx format because that's the name of the app that was provided with DML when that format was first supported but GCIT and DMToolbox can also convert into this format. The benefit is that it is both usually smaller in size like the DiscEX (trimmed) format mentioned above and it often has faster loading times in game.
