I recently acquired a Genesis console with a couple of games... I have an RF switch, but no power source. I've read online you can use a NES power source, so I tried that, and the Genesis seems to power up (the LED comes on). But all I get is a grey screen. I have a SNES that shows the _exact_ same 'symptoms'. Does anyone have any clue as to what the problem is, and if it's easily fixed? Thanks much in advance!
