Guilty Gear X [By Your Side "G.Gear"] GGX Extra Type A / Guilty Gear X [By Your Side "G.Gear"] GGX Extra Type A / Guilty Gear X [By Your Side "G.Gear"] GGX Extra Type A

T-2401M is the catalog number for the game, as this extra CD came only with the limited edition of the game "GUILTY GEAR X" for SEGA Dreamcast.

There was also 4 types of CD offered at the time, named "TYPE A", "TYPE B", "TYPE C" and "TYPE D". This one is the "TYPE A" version.

Each of them has the same track but with different: shapes / arts / bonus wallpapers; there is 2 distinct wallpapers (800x600 bmp) offered per CD that are different from the ones you can find in the game's GD-ROM.

The track it contains is also the same one you can find in the "GUILTY GEAR X HEAVY ROCK TRACKS ~ The Original Sound Track of Dreamcast!!" album (named "NO MERCY ~Sol VS Ky Theme~).
