Nice! I hope you’ll give us progress updates etc.!

You should do the expansion audio mod so you can experience Famicom expansion audio when you use an Everdrive N8 (or is it only the N8 Pro that supports expansion audio) flashcart. It’s just a resistor and wire that you solder on to one of the expansion port pins, its very easy. Though voultar and others seem to think just using a resistor adds noise to the audio circuit (while pushing their “much quieter” and much more expensive custom mods), I have not had that experience (or maybe I don’t notice or care). Voultar makes great products, but at least in this case, I see no need to spend a single penny more than the cost of a resistor, a wire, and some shrink tubing to protect against shorts.

EDIT: Also, you probably know this, but BOIL YOUR CART CONNECTOR if you have a flashing light and be sure to thoroughly clean any game you put in the NES. Do not bend the pins! This is starting to be old news, but I am reading about way too many people who still don’t know about boiling the connector and talk about bending pins or buying a cheap china replacement cart connector.
