This is a used copy of X-Men vs. Street Fighter for the Sega Saturn, confirmed to work with both the software and the 4MB expansion RAM. The instruction manual is starting to show some wear, so it's been protected with plastic wrap (still readable). Please note that the expansion RAM needs to be inserted halfway to boot, as per Sega's specifications. The disc is in good condition. This item is for those who understand it is a used product. - Title: X-Men vs. Street Fighter - Manufacturer: CAPCOM - Memory Card: 4MB - Genre: Fighting - Compatible System: Sega Saturn Thank you for looking.
