GDIファイルとは？
A GDI file is a plain-text descriptor file used by Sega Dreamcast emulators, such as Redream and Flycast. It lists the contents and layout of a Dreamcast GD-ROM disc, including the order of tracks and the location of the data stored in accompanying .BIN and .RAW files. Together, the GDI file and its referenced files form a complete copy of the original game disc.
詳細情報
Gamers and preservationists may use GDI files to play or archive Dreamcast titles. When a Dreamcast emulator loads a GDI file, it reads the file's track list and then loads the corresponding BIN and RAW files to run the game. This format is generally preferred for emulation because it preserves the disc's original layout and data structure.
An example GDI file might look like this:
3
1 0 4 2352 track01.bin 0
2 45000 0 2352 track02.raw 0
3 45150 4 2352 track03.bin 0
This example shows a three-track disc where each line tells the emulator which file to load, what track type it is, and where it begins on the disc.
GDIファイルの開き方
You can open GDI files with various Dreamcast emulators, including Redream and Flyinghead Flycast. Since GDI files are text-based, you can open them with text editors (this is not the same as opening them with emulators). For example, japanese-cake GDROM Explorer can view GDI files.
