The Game Boy Advance saw many SNES ports, and Capcom decided to bring Final Fight back. The result is Final Fight One, a version of Final Fight released in 2001 that isn't just a simple port, but a special edition which fixes the problems of the SNES version, and also adds lots of new content. Final Fight One has all of the levels from the arcade version, along with all the playable characters and a 2 player link mode. Unlike in the SNES version, more than 3 enemies can now appear on screen.
But that's not all. Unlockable extras include two extra versions of Cody and Guy, using their sprites from Street Fighter Alpha 3, who are a ton of fun to use due to them being very powerful. Before each boss fight your character will have a brief talk to the enemy, and some of the conversations are amusing, especially any with Sodom. Cheats exclusive to this version include a level select, and extra costume colors for each character.
The only shortcomings with this version are with the music -I just don't particularly like the score for this version, and sometimes tracks are used in the wrong places. There are also a few little minor flaws, such as the elevator ride in the last round being missing. These are all small faults though and Final Fight One is one of the better versions the game you can buy.
