What is a .GDI file?

The file extension .GDI is associated with the Dreamcast Gigabyte Disc Image, which is a specific type of file used primarily for emulating Sega Dreamcast games on a computer. This file format is created to store an exact copy of the data from original Sega Dreamcast game discs. Inside a .GDI file, you might find other files such as .BIN and .RAW, which contain the game's data and audio/video information respectively.

To open and use .GDI files, you need specific software designed for running Sega Dreamcast games on other platforms, such as computers.
