i know that the all nintendo RF cables are the same, and they work with every nintendo system, so i know the power of the system isn't really an issue. but i was wondering if i could use an RF cable for my gamecube that's not by nintendo. could i, or would it ruin the system? i hate taking risks, so please be 100% positive that any old RF cable would do. i'm sure trying it wouldn't hurt the system, it just wouldn't come out on my tv, but still, i hate taking any risk whatsoever. thanks in advance!
