First, you should know what M.U.G.E.N is. M.U.G.E.N is a free, non-professional 2D fighting game engine that only made for personal use on DOS, Windows and Linux platforms. Its was developed by Elecbyte group using the C language and Allegro libraries, and gives the characters from different ACG (Animation, Comic, Game) a common platform to fight with each other.

FB Alpha (short for FinalBurn Alpha, FBA for short) is a very popular multiple-console emulator for MC68000/Zilog Z80 based arcade games. It has less system memory and lower computer configuration requirements than MAME, and runs faster with better graphics - comes with all features of MAME Plus!. One word, its position in video gamers' mind is now only after the king of arcade emulator MAME.

As a big fan of Sango series game, I have almost played all the related games of this theme on most platforms. From handheld to arcade, and from MS-DOS to PC. Although it has been too many times, yet I still enjoyed that.
