@Sean nice timing =) Both S5+S6 are wired to Pause? Or was it a typo?
Yeah, I was trying to get it in before the deadline, but had trouble cleaning the die. I'm not sure if I'm overheating the epoxy when I'm de-globbing them, or if it's a different epoxy that doesn't react to nitric acid the same way, but 5 of the last 10 Tiger dies have had plastic on them that I couldn't remove with nitric acid, even after multiple washes. So I tried sulfuric acid and that worked. I reduced the amount of time that I put them in Whink to remove the top metal layer, but I went too low and had to clean some of them twice, then bumped it back up and it was a little too long.
S5 and S6 are tied together. Also, there were 3 sets of traces under the action button, but it only had a contact for the center one. The top one was connected in parallel with the center one, but the bottom one was connected to K2. I'm not sure if they reused a PCB or if they simplified the game and removed a button.
