CDI games, also known as Compact Disc Interactive games, are a type of interactive media that combines the features of CDs and video games. These games use a special format that allows for the storage of audio, video, and game data on a single CD. CDI games were designed to take advantage of the Dreamcast's built-in GD-ROM (Gigabyte Disc Read-Only Memory) drive, which enabled the console to read and play CDI content.

Write Speed: Lower is better for reliability. Aim for 8x or lower (some recommend half the rated speed of the disc).
The Technical Backbone: Understanding the Format To truly appreciate a CDI collection, one must understand the technical significance of the format. Unlike the standard ISO format used for many CD-based systems, the Dreamcast utilized the proprietary GD-ROM (Gigabyte Disc) format, which held roughly 1.2 GB of data. When the preservation community sought to backup these games for emulation and archival, the standard CD-ROM ISO format was insufficient.
