so i got a nes a little back now for £10, wasn't worried about it working as i had my own.
i finally got around to testing it today, only to find nothing happening, expecting the worst i thought i'd crack it open to take a look around (also to see if i could salvage the 72 pin connector :P
That's great you were able to get it working again, and a great deal at that price!
I have one of these Blinking Light Kits (//https) from the Kickstarter that I backed but haven't got around to installing it yet. I should really do that this weekend and try it out.
