The original Capcom Vs. SNK was a big hit, and a sequel arrived a year later. Capcom Vs. SNK 2 was released in 2001 for the arcades and quickly became another success story, with the usual improvements: more characters, more moves, more super combo options etc. The good news for Final Fight fans was that Rolento had been included as a playable character. He's got the same sprite and moves he has in Street Fighter Alpha 3, but has had his speech re-recorded. As in the Alpha games, El Gados sometimes appear in his win poses.
However Rolento wasn't the only Final Fight character added. Maki from Final Fight 2 was also added! This was the first time the character was used in a new game since Final Fight 2, which had been released 8 years previously. Maki is equipped with a tonfa (her weapons of choice in Final Fight 2) and has a combination of all new moves and some techniques similar to Guy's. She can still do her gale wind kick, and it still costs some health to use, as it did in Final Fight 2.
Capcom Vs. SNK 2 was later ported to the Dreamcast (in Japan only) and Playstation 2. Ports were also released for the Gamecube and Xbox -these versions were called Capcom Vs. SNK 2 EO, and featured a new control scheme which let player perform special moves and super combos much more easily. Capcom Vs. SNK 2 is a very popular game with fans, and there have been calls to see a re-release for current gen consoles. This hasn't happened yet, but hopefully it will some day.
