Hello people! I had a "polystation" famiclone that had both rca and RF outs. But the weird thing is, i didn't needed to hook it up to the TV to play it, if i just turned the console on and tuned my television to channel 3 I could see the picture, even if with a medium quality. What caused this? I'm sure that are some clones that use an antenna to transmit the image to the TV, but mine used just cables. Was it just bad RF shielding, and it happen in other consoles?
