missing cover art
This game was released twice! Four games released by Midway back when they first started making Dreamcast games had several errors, which were fixed in subsequent pressings. How do you tell if you have a fixed copy? The cover should should say "Hot! New!", the disc is slightly different, and the UPC may also be different.
The other games that were released as Hot! New! versions were Mortal Kombat Gold, Hydro Thunder, and Ready 2 Rumble Boxing.
