Workflow
The usual workflow to make self-bootable disc for the Dreamcast is as follows:
- Build your source (usually using KallistiOS)
- Transform your .elf into binary
- Scramble the binary
- Build a .iso image from a directory
- Transform the .iso into a .cdi image
Linux
This is an example for automating the .cdi image process under Linux. Consider this more like a template as you'll need to edit the paths, names, etc to your own project.
#! /bin/sh PROJECT_DIR=$PWD/build PROJECT_NAME="Project_Name" TARGET="main.elf"
# Build your program # This assumes that you can properly build your source code. The program main output will be $TARGET make $TARGET
# Elf transform sh-elf-objcopy -R .stack -O binary $TARGET output.bin
# Scrambling process $KOS_BASE/utils/scramble/scramble output.bin 1ST_READ.bin
# Creating a .iso image from a directory # Make sure you have a working IP.BIN in your current directory. Or change IP.BIN path to wherever you like. # Useful option for mkisofs is *-m* which allow to exclude files from the iso image (useful to remove .git, or some other folder) mkisofs -C 0,11702 -V $PROJECT_NAME -G IP.BIN -r -J -l -o $PROJECT_NAME.iso $DIR
# Transform your .iso into a .cdi $KOS_BASE/utils/cdi4dc/cdi4dc $PROJECT_NAME.iso $PROJECT_NAME.cdi
