One other question: What's the difference between the regular and deluxe audio bridges? That doesn't seem to be explained on the campaign page.

Comments

It's on the campaign updates & comments, but not the main page. That should be rectified, indeed.

The deluxe one has a knob to control the mixing level so that any of the classical Famicom games with expansion audio can be fine tuned.

For Former Dawn specifically, all you need is the regular one.
Awesome, that helps a lot! Thanks! :)
