If you have more than 25 years is very likely that you have at least once in your life, "roasted" a good Euro (or shells) in arcade games. It is also very likely to be one of those games from Capcom.
Capcom, between the 80s and late 90s was the publisher of video games that had more success in arcade games, especially with the Street Fighter series of games or other games like Final Fight, the 194X series, Ghosts n 'Goblins, etc ...
Today, many of these titles are considered classics of retrogaming and continue to make the same desire to play, but with the passage of time and the evolution of game consoles, the halls of games where we played have been disappearing. However, you are a Porreiras Capcom (and smart too) and released some time ago two compilations of classic Capcom for the PSP.
