makeivs-ng is a command-line utility for creating ISO 9660 CD-ROM images. Unlike simpler tools like `mkisofs`, makeivs-ng offers advanced features such as support for handling bad sectors, adding dummy files for specific sector counts (often required for video games), and customizing the ISO's metadata like the application identifier.
The utility is designed to create ISOs suitable for various purposes, including archiving data and creating bootable CDs or DVDs.
It allows precise control over the resulting image structure, making it well-suited for creating disc images for emulators or devices that require specific ISO formats. makeivs-ng is commonly used where other ISO creation tools lack the necessary fine-grained control over the ISO image generation process.

The exact set of available options and their behavior might vary slightly depending on the specific version of makeivs-ng installed. Always refer to the command's built-in help or manual page for the most accurate information.

makeivs-ng is often used in the context of creating exact replicas of CD-ROMs for use with emulators or on embedded systems. Certain emulators and hardware platforms require specific ISO image structures or require images of a particular size. makeivs-ng gives the user the required control to meet such needs.
