This is a really nice way to get a Game Boy Macro finished up. I had it all working perfectly, but the wires that come on the Switch speaker are really fussy and I had to resolder the speaker multiple times and now I've fried the contacts for the speaker. YAY! Now I have to order another to fix it! I have better wire, so I don't think I'll have any issues next time.
So, bottom line is: It's a rad thing, I just messed mine up. Lesson learned!
