Guys I need some advice.
Today I was moving my consoles to a new shelf, rearranging the cables and power supplies. I made the stupid mistake of plugging my NES AC 9v power supply into my RetorN3 NES/SNES/Genesis famiclone and turned it on for about five seconds before realizing what I had done. Sure enough, it doesn't work now. The RetorN3 uses a 9v center pin positive DC plug.
Is there anything I can do to remedy my mistake? The RetorN3 has a standard 7805 voltage regulator which I'm assuming is kaput. Would replacing it restore the system to working order? Anything else? The system never exploded, popped or started smoking and I I've immediately taken it apart and examined the boards and don't see any signs of stress, burns or other damage.
I feel mad at myself, but it was honestly a simple mistake and I'm hopeful I can correct my mistake rather than calling the system a write off.
