I've done three:
- Added expansion audio to two different NES consoles. Used a 47k resistor to connect two specific pins. Akumajou Densetsu sounds amazing. Pic: https://twitter.com/...817194742960130
- Removed a resistor at R31 on a VA2.3 Genesis model 2 and created a solder bridge. That raised the volume level of the square wave PSG channels so that the audio is almost perfectly balanced. At the very least, Streets of Rage 2's bar fight scene has a melody again, and that's good enough for me. Pic: https://twitter.com/...865528718680065
- Removed the 12v rail from my Dreamcast that has a GDEMU clone in it. Stuck it in a baggie and stashed it in the system for safe keeping, in case I ever want to put the GDROM back. No picture, got too excited to try it out. Really does seem to help heat levels.
I've also done full-body scrubs on a couple of Genesis consoles I picked up recently, used 91% isopropyl on a couple of cartridges, and swapped the shells around on a functional but nasty Dual Shock 2 and a fairly nice but dead Dual Shock 2, so now I have one that looks nice and works well, and another that needs LOTS of love.
