How to Create a Homebrew ISO9660 Bootable Disc for Your GameCube

If you're looking to create a homebrew game or app that can be played on your Nintendo GameCube, then creating a bootable disc is a great way to do so. But did you know that it's possible to place your own apploader in an iso9660 disc and keep the disc iso9660 standard? In this article, we'll show you how to create a homebrew iso9660 bootable disc suitable for the GameCube using a Linux PC.

To start with, let's understand what an iso9660 disc is. An iso9660 disc is not bootable by default and usually has its area zeroed. However, a GameCube disc contains a boot program called the apploader at a fixed position in the disc that gets called by the IPL to load a main executable program of the disc.

The location of the apploader in a GameCube disc falls within the System Area, which is not part of the iso9660 specification. This means that this area can be used for whatever particular purposes are needed. The iso9660 specification requires discs to have a reserved area of 16 sectors (the so-called System Area) at the beginning of the disc.

You may also be aware that you can build bootable discs using other operating systems, but this guide will focus on Linux only. Creating a homebrew iso9660 bootable disc for your GameCube is possible and can be done directly by both modchip and softmod IPL replacements, as well as through drivechips using the original IPL.

To create a homebrew iso9660 bootable disc, you'll need to have a Linux PC and some basic knowledge of disk formatting. Once you've formatted the disc, you can place your own apploader in it and keep the disc iso9660 standard. This will allow you to boot your homebrew game or app directly on your GameCube.

In this guide, we'll walk you through each step of creating a homebrew iso9660 bootable disc for your GameCube using a Linux PC. With these instructions, you should be able to create your own homebrew game or app and play it on your GameCube. So let's get started!
