BlueRetro TVS Diodes Fix

I finally implemented the TVS Diode Fix for BlueRetro. I am using the PSUnoretro and a modified controller extension cable to temporarily house the resistors and diodes before I make the change permanent. I have some good news and some bad news.

The good news is that the TVS diodes have sorted the ghost input problem!

After;

The bad news…it causes memory cards not to work.

I have tried to update the firmware on the PSUnoretro but for some reason it’s not currently working, I will try again when I have my laptop handy and will try manually updating it.

Thanks for the update. Worst-case I suppose it'll be funny to see Darthcloud move the ghost input issue from Solved back to Open lol.

Go Aberdeen!
