==Introduction==
This guide explains the necessary steps to produce a homebrew iso9660 bootable disc for the Nintendo GameCube.

It can be booted with any modchip or drivechip installed and through IPL replacements like GCOS or Swiss.

==What you need==
*A working PC with Linux or Windows
*A homebrew dol program, that will be booted
*dolLZ 3 or udolrel (dolLZ preferred)
*A gbi.hdr file
*mkisofs

==What you may need, depends on your needs==
*A DVD Writer and a (mini)DVD-R
*A Drive Replacement like Wiikey Fusion or WODE
*A SD(HC) Card

==Making a bootable disc==

We will build an iso9660 image with the "El Torito Specification" boot extensions, with a Boot Image (''gbi.hdr'') and with a DOL file we want to boot (''bootldr.dol'').

1. Create the a directory with the following structure:
homebrew_disc\gbi.hdr
homebrew_disc\disc\

2. Copy all files you want to include in the disc to the "disc" directory. The directory must not be bigger than 1.35 GB.

For example: If you are creating a SNES emulator disc, you can add your rom files to a "rom" folder inside the "disc" directory.

3. Relocate the DOL program you want executed during disc boot
dollz3 my.dol bootldr.dol -m

4. Move the "bootldr.dol" to the "disc" directory

5. Build the iso9660 disc image.
mkisofs -R -J -G gbi.hdr -no-emul-boot -b bootldr.dol -o homebrew_disc.iso disc/

6. Burn the image you have created to DVD-R media or transfer it to sd card or hard disc for use with swiss.

==Additional steps for WODE==

The WODE will not load gamecube iso's that are too small.
So it could be necessary to add a dummy file to increase the iso size.
You can use ''DummyFileGen'' for this.
I do not know the minimum size for use with the WODE, but yamaharacer tested a disc created by me with a 100mb dummy file and it works, maybe smaller dummy files will work too (further investigating required).

==Additional steps for Wiikey Fusion==

If you created a simple homebrew disc iso with just the hombrew dol on it, it could be useful to use my header faker.
The reason: All gamecube images added by the ''WBFS Manager 4.0'' will use 1.35 gb on the wbfs partition.
If you use the header faker, it tricks the Wiikey Fusion / WBFS Manager so it will only take 2 mb on the partiton.

==Booting a bootable disc==

In order to boot the homebrew disc built, use the appropiate option of your GameCube IPL replacement (GCOS, NinjaShell, Qoob, Viper, ...) or direct boot it through XenoGC or DuoQ.

==Additional Information==

This Howto is based on [http://www.gc-linux.org/wiki/Building_a_Bootable_Disc this] one (thx gc-linux.org)

It has been tested by me with Swiss r52 and XenoGC.

A sample package (gbi.hdr, swiss r52 as bootldr.dol, mkisofs, dollz3) can be found in the forum ([http://www.gc-forever.com/forums/viewtopic.php?f=3&t=657 here])
