Capcom (株式会社カプコン Kapukon Kabushikigaisha = Capcom Co., Ltd.) is one of the most successful video game companies in history releasing to the arcade, console, and PC markets. They have created several successful franchise like Mega Man, Street Fighter, Resident Evil, Devil May Cry, Breath of Fire, and Monster Hunter.

Capcom is short for Japan CAPsule COMputers.


Music Development


Capcom's early arcade titles used a variety of different sound drivers, before eventually adopting one designed by Toshio Arima as their standard driver circa 1985. After a couple of years, Yoshihiro Sakaguchi created an updated driver, which continued to be used in various forms (often customised by other programmers) up until around the early-mid 1990s.


The majority of Capcom's NES games use a sound driver written by Yoshihiro Sakaguchi in 6502 assembly to produce sound on the audio processing unit of the CPU of the NES, the RP2A03. Composition required musicians to arrange their music into a custom Music Macro Language using hex values, a very tedious process. Capcom's sound driver was quite robust and yielded an distinctly identifiable sound.

It is unknown if the earliest NES Capcom games used the same driver, as the composers have given differing reports as to whether they used Sakaguchi's driver or one by Micronics programmer Kazuo Yagi, but it is known that the last few games use a sound driver created by Make Software rather than Sakaguchi's driver, possibly because it was easier to work with.


Toshio Kajino designed the first sound driver used for Capcom's SNES games; his driver may have been a heavily modified version of Nintendo's Kankichi-kun driver. After about a year, this was replaced by a new driver designed by Yoshihiro Sakaguchi with assistance by Yasushi Ikeda, which was used for the remainder of their SNES games - with the exception of Street Fighter Alpha 2 (SNES), which for some reason uses a Kankichi-kun-derived driver, possibly programmed again by Kajino. Instrument samples were provided by Tatsuya Nishimura, who had just departed from TOSE.

Game Boy Advance

The company used Nintendo's MP2K sound engine.
