As I understand the ENIO project it's a breakout board for the expansion port of the NES. There are plans for other hardware but it's still a WIP.
As to expansion audio, I have seen a simple mod to the exp port pins/mother board connections to route the cart audio to the on board audio path. I know PowerPak users can take advantage of this, but it has limited use with official NES game titles.

I spent a good part of my day researching NES audio expansion and quickly found out a whole bunch of things...I saw people with Powerpaks that were able to emulate chip expansion when they use Famitracker, people talking about audio expansion here on the forums using the ENIO, others modding Powerpaks with additional chips for sawtooths on the NES with subpar results, others like No Carrier reported they had no issues with it.
Just a whole bunch of options and possibilities. I know that in order to utilize chip expansion, first you need software that allows it and as far as I know, Famitracker is the only program that allows you to write for additional NES chips...I don't use Fami but I'm trying to gather as much knowledge as possible.
What I'm getting at here is it's probably unrealistic to see an update of Pulsar that adds FM synth abilities, but some of these chips allow the NES to use more pulse channels. I'm not saying I wan't Neil to jump to my expectations but I would love to see the NES's triangle channel bypassed for a more useable third pulse channel. I know nothing of coding trackers, but all the channels in Pulsar share the same instrument editor page...In my mind it would seem like a realistic thing to code Pulsar to allow a third pulse with the right expansion.
