EPSM (Expansion port sound module) For the NES?

[JudeATI]

Do you think that you guys can add the EPSM to the NES? It is a Home brew device to the NES that plugs into the Unused expansion port on the bottom of the NES and adds the Sunsoft 5B chip and the YMF288 in drums mode which is a lower powered version of the YM2608 and cannot do samples (and at least for FamiStudio it only allows NTSC). There is a whole page about in the the NES Dev Wiki on how it all works if you are intrested.

It's kinda pointless, since YM2608 is already present, and YMF288 is just YM2608 that lacks the additional sample channel. You could just add 2A03 and YM2608, hide the additional sample channel of YM2608 and go on making your song.
