The Dreamcast version added the new game mode, Cross Fever, which permitted four-player gameplay. The game later received a PlayStation port. However, the console's RAM limitations required the developer to remove certain features, most notably the game's tag team element; thus, most game modes were restricted to two-character battles, instead of four. This reduced the player's secondary character to an assist role, similar to guest characters. To overcome the limitations, the PlayStation version had to implement a new gameplay mode called Cross Over. Cross Over Mode allows tag team play by forcing the players to fight with identical teams. For example, if Player 1 chooses Spider-Man and Player 2 chooses Ryu, then Ryu and Spider-Man would automatically be selected as Player 1 and Player 2's secondary characters, respectively. The game also added an art gallery, where players could view game art and ending animations. Many frames of animation were also omitted as a result of insufficient RAM, particularly in larger character sprites. "Marvel vs. Capcom: Clash of Super Heroes" debuted in Japanese and North American arcades in 1998. The game was released on the Dreamcast on March 25, 1999 in Japan, and October 7 in North America. A European version for the Dreamcast, published by Virgin Interactive, was released on June 23, 2000. The game was ported to the PlayStation on November 11, 1999 in Japan, where it was renamed "Marvel vs. Capcom: Clash of Super Heroes EX Edition". North America and Europe received the PlayStation version later in January 2000. A high-definition version of the game was released, alongside "Marvel Super Heroes", as part of the "Marvel vs. Capcom Origins" collection. Built using the arcade ROM, the compilation sought to maintain the original's gameplay experience, while adding new features such as online multiplayer, challenges, and replay saving. It was released through the PlayStation Network on September 25 in North America and October 10, 2012 in Europe. The Xbox Live Arcade version was released worldwide on September 26. Following the apparent expiration of Capcom's licensing contracts with Marvel Comics in 2013, "Marvel vs. Capcom Origins" was removed from online stores in December 2014. In June 2020, "Marvel vs. Capcom" was included in a home arcade cabinet from Arcade1Up alongside other games like "Marvel Super Heroes vs. Street Fighter" and "X-Men vs. Street Fighter". Toy Biz produced a line of action figures to help promote the game, which consisted of four two-packs, each of which featured one Marvel character and one Capcom character.
