Different games have different resolutions is why some of your games are not going to work through composite on that tv
I think, for now, I'm just going to stick with the RF/Coaxial hookup. The picture isn't that bad, and after toying with the wires so much, I'm pretty sure the digital "noise" I'm getting is because of my cheap NES RF switch. I'll probably head up to Vintage Stock and shell out the $4 to get a Nintendo brand one.
When I have some free time, I'll start perusing the free listings on Craigslist and hopefully find one of the early tube HDTVs, like one of those giant Sony Trinitrons. I know the SNES works on those for a fact, and it would make a great retro gaming TV.
Again, thank you mickcris, mkiker, and everyone else that helped me out with this problem!
