The American first edition came with a playable demo of Devil May Cry on a separate disc. There are two disc label variants, Devil May Cry Demo Disc or Devil May Cry Demo CD, both SLUS 29009 with the same playable code.
The game disc and paper items seem to be identical in both cases. The front, back, manual, and game disc scans on this page were scanned from a game with demo variant 1.
Pre-ordered copies came with Resident Evil Code: Veronica X Wesker's Report.
