I'm currently working on a restoration of another classic Stern, this time a Trident. I'm wondering if the second version of the RoyGBev card works with the Trident, or is it only really intended for SB-300 games (like Meteor)
I'm also curious if there is a way that I could add a second toggle switch, that would allow transitioning between the SB-100 (or sb-300 on a Meteor) sounds in the new code and the wave trigger sounds. Is there a pin available to use to set a variable in the code to allow for this?
