Slightly off topic...

I have some consoles plugged through an RF daisy chain

Order goes from first to last:

Saturn > SNES > N64 > NES > Mega Drive.

I found that the Mega Drive using it's standard RF connector, was incredibly fuzzy and the signal was very weak. I then decided to use the Master System's RF and the picture cleared up significantly (though it's still not perfect).

My point is that when doing a daisy chain, you can get them to go for longer if you put the RF in a certain order and sometimes use different ones (my N64 uses a SNES RF unit instead of it's standard one).
