I recently bought an NES (which I was told was fully functional) hoping to have some fun playing some games.
However after getting a cartridge (Mario bros & Duck hunt combo cartridge) the system flashed a blue screen and reset constantly. From what I knew this was because it was either really dirty or the 10nes chip had gone bad.
I thoroughly cleaned the system and cartridge which removed a lot of dirt however it still didn't want to function. The only plausible explanation was the 10nes chip so I followed various tutorials on disabling it by removing the 4th pin.
Unfortunately I accidentally damaged the 5th pin in the process, so in addition, is my NES even more dead than it already was now or is it still recoverable?
Side note: The 72-pin connector was cleaned too (it was not dirty at all) and all the pins were in good shape.
