I've noticed in MAME some of their arcade games ran on Konami CPUs..!
Wow !! Wonder why Konami still hasn't made any of their own gaming system yet. Even Nintendo and Sega does not have their own CPUs (only modified version of existing CPUs).
The PlayStation (s) have their own Sony CPUs, but Sony is a general purpose electronics company, and not just a gaming company.
