Well, I messed up. I have a Retro Duo console (black cmbo SNES, NES) I have only used it once, it worked fine, I moved and accidently plugged in the wrong a/c adapter, I realized it when the lights started to flash. It uses a 5 v adapter, I plugged in a 12 v , it was only left in for about 30 seconds, the lights flashed and I unplugged it. I replaced the a/c adapter with the actual one an tried it out.The colors for the sysytem lights had swapped, the 8 bit was green and the 16 bit was red, its supposed to be the oppisite. The games would not display, I tried the system with different cords, with different tv's and nothing, I know I am probably putting off the fact that I fried it, but does anyone have any info, on what damage I may have done, or what if anything there may be that I can do to repair it. Thanks for the help...
