This might be a controversial opinion but I've found that with my Wii/CRT tv setup I get the scanlines no matter what resolution I have it set on as long as the vertical number is 224 or 240. I've read a lot of stuff about finding out what the exact resolution of the game you're emulating and then doubling the horizontal lines to make it perfect, but I've found that this is unnecessary & that the system is far more adaptable than people think.
Also because I have a flat screen CRT the Wii has a terrible problem with cutting the edges off the top and sides of the screen. But I've also been able to largely remedy that by selecting 19:14 as the aspect ratio instead of 4:3. Also I recommend selecting either 576x224 or 608x224 if you are using a CRT, especially if it's flat screen. I've read that some Samsung modern tvs are capable of processing 240p but I'm not sure what the optimal settings would be for that.
