The Credit Opacity Problem
Early Capcom NES titles (1985–1988) were produced in an industry era where composer credits were treated as internal business information rather than public attribution. Some titles included staff rolls accessible at the end of gameplay; others did not. Where staff rolls exist, they must be reached by playing the game to completion - a non-trivial requirement for GnG NES specifically.
The VGMPF community’s approach to credit verification:
- Play or emulate the game to its credits/ending sequence
- Document the staff roll text verbatim, with screenshot evidence
- Cross-reference the credit against other known Capcom NES team members
- Cross-reference against MobyGames and VGMDB for additional corroboration
- Note confidence level: Confirmed / Probable / Unverified
Japanese-Language Primary Sources
For Capcom NES era composers, Japanese-language primary sources are the most valuable research materials: Famitsu issues from 1985–1988, Capcom internal documentation (rarely available publicly), and developer interviews in Japanese game magazines.
Masashi Kageyama interviews in English are essentially unavailable. Japanese-language Famitsu interviews from the era may exist; these would require both access to the original magazine archives and Japanese-language translation. The Shmuplations project has translated various Capcom developer interviews, but coverage of Kageyama specifically has not been confirmed.
