My friend has just ordered a bunch of PCBs and some components for these. The plan is to sell them either by by just the PCB (~25 EUR), PCB and a surface mounted component pre-soldered + some odd DC-DC coupler (~40 EUR) or pre-built ( ~200 EUR, with a custom laser-cut wooden case, without SID). We'll set up an ebay store or something once the boards and components have arrived, and until then, nothing of this is really "final." .

For what it's worth, I went with an op-amp style (Cmoy-inspired) solution. First attempt was using a home-made board but I have now made an SMD version that is a good deal smaller. I like using an op-amp because it would sacrifice itself before you end up doing any damage to your CPU itself (say due to static from plugging in an audio jack or something).

The downside is that it needs power. My first design required a separate power brick but I found a low voltage op-amp from Texas Instruments (Burr-Brown) that can be fed with low enough voltage that I can just use one power brick into the NES and tap off those inputs. That requires using a DC power brick though (the original NES power brick is AC), but a nice clean linear regulated power brick should work just fine, if not better, than the original power brick anyway.

You can see my first attempt here:

Still waiting on parts for my new board so I can't claim success for it just yet.
