DuckTales the unknown composer, a new solution?

[depa]

Well, I decide to make some research to solve the mistery of DuckTales composition.
Looking on some japanese sites, it could be plausible (but not a final proof) that Hiroshige "Pero" Tonomura composed the music for the game. Links here & here.
I've find also this quote on twitter

The music of DuckTales sounds very similar to "Pro Yakyuu? Satsujin Jiken!", which was composed by Hiroshige Tonomura...

Tonomura moved to Taito from Capcom in 1990, while Duck Tales was developed on 1989, it could be one of his final works for capcom.
Does anyone have linked DuckTales to Tonomura before?
