Homebrew, when applied to video games, refers to software produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs. Many consoles have hardware restrictions to prevent unauthorized development.
GD-ROM is a proprietary optical disc format originally used for the Dreamcast video game console, as well as its arcade counterpart, the Sega NAOMI and select Triforce arcade board titles. It was developed by Yamaha to curb piracy common to standard CDs and to offer increased storage capacity without the expense of the fledgling DVD-ROM. It is similar to the standard CD-ROM except that the pits on the disc are packed more closely together, resulting in a higher storage capacity of 1 gigabyte, a 30% increase over a conventional CD's capacity of 700 megabytes.

The Dreamcast VGA Box is an accessory for Sega's Dreamcast video game console that allows it to connect to a video display such as a computer monitor or an HDTV set through a VGA port.

MIL-CD or Music Interactive Live CD is a compact disc format created by the video game company Sega in 1998. The main purpose of MIL-CD was to add multimedia functions to music CDs, for use in Sega's Dreamcast video game console. For example, MIL-CD music releases were to feature enhanced navigational menus, internet capabilities, and full-screen video. It was similar to tests done with Audio CD/CD-ROM combo discs on PCs, DVD-Video/DVD-ROM combo discs on PCs, game systems and DVD Players, as well as game/video combo discs for systems like the PlayStation 3.
The Super NES CD-ROM is an unreleased add-on for the Super Nintendo Entertainment System (SNES) video game console. It was built upon the functionality of the cartridge-based SNES by adding support for a CD-ROM-based format known as Super Disc.
