Would it be possible to play a reproduction cart of a NES game that utilized an external sound chip? Specifically I'm wanting to get repros of Akumajou Densetsu and Mouryou Senki Madara, which both use Konami's VRC6 sound enhancer. (I think they might be the only games to use it O_o)
I've heard that the NES doesn't have the capability to utilize these external mapper enhancements but I thought I'd check.
