Making Homebrew CDI/GDI Images

[DLDrago]

I'm probably missing something obvious here, but I can't seem to find a way to make a homebrew image. I'm looking for a solution that uses Ubuntu Linux 20.04 on Windows 11's Subsystem for Linux.

For homebrew CDI images, check out mkdcdisc, a newer tool that's part of the Simulant project. It's a really simple command-line tool that takes an ELF and gives you a CDI.

For homebrew GDI images, this is a little more complicated. GDI files represent GD-ROM images, but KalllistiOS out of the box won't read GD-ROMs as the original author wanted to prevent piracy and never foresaw a future in which people would make their own "GD-ROMs", so you'd need to patch KOS for your homebrew project to be able to read the disc. Use GDIBuilder, and make sure your 1ST_READ.BIN is not scrambled as a GD-ROM doesn't require that.

Got it. I'll use a CDI with that.

I have been beating my head against the wall trying to get mkdcdisc to work. I followed the setup instructions at https://gitlab.com/simulant/mkdcdisc but each time I try to use it I get the error "/bin/sh: 1 mkdcdisc: not found." Is there something special that needs to be done that I am missing?
