Donnie Darko: The Director's Cut


Mega CD ISOs 
Below you will find ISOs for Sega's Mega CD console. The best emulator for these ISOs that I'm aware of is Gens. The MP3s that are meant to accompany these files will soon be put in the "Music" section of SonicStuff. WinRAR is needed to extract these files.

MUSIC FILES NEEDED FOR THE ISOS CAN BE FOUND IN THE MUSIC SECTION OF SONICSTUFF, UNDER "GAME RIPS AND REDBOOK AUDIOS".
