There's no easy way to output it to a CRT TV. Converter boxes won't do it, because they can't output a 240p signal, only 480i at best, and your games will look terrible like that - not to mention the output lag; I bought one and it was simply terrible, lots of flickering and the minimum it could go was 800x600, complete garbage. I think the only way is using one of those Arcade VGA graphics card that output 240p, but they're just... really expensive and not easy to use.
I say: Get a CRT MONITOR, as in, an old computer monitor, and not a CRT TV. They are smaller, CHEAP, and they will look even better than a CRT TV, as they will obviously take VGA cables and you can adjust it to 240p, using a filter for interlacing. Retroarch does the job, and it looks pretty damn good, much better than you'd ever get with composite:

You don't need to set 25% scanlines at all, you just need to adjust the Overscan. I don't know how ZMZ handles that, but basically, SNES with Overscan on = 240 pixels native, as it adds black borders top and bottom, so no stretching or anything else needed, it's basically the pure image. When you set it to crop Overscan, it'll be 224 pixels only.tried that yesterday and man... looked fantastic, very crisp image and with natural scanlines.
I set my Samsung Syncmaster 551v to 2048x240, launched zmz(with snes9x core, scanlines 25% to force 224 pixels height or else the game was stretched to 240.
Isn't it funny how we grew so accustomed to CRTs that we think that half the screen being darker looks better/normal?
the overscan option doesn't exist on ZMZ, the only solution I found was set 25% scanlines, think on ZMZ as ZSnes interface but with the Snes9x or bsnes core.You don't need to set 25% scanlines at all, you just need to adjust the Overscan.

Well in an actual CRT there's glow as well as color blending and bleeding that compensates for that, in the end the screen doesn't look darker at all. In fact it'll look brighter than your usual emulator image depending on how you adjust it.
Well that's what I thought. Well if it works OK that's fine. Does it stretch the image to the correct 4:3 aspect ratio at least?the overscan option doesn't exist on ZMZ, the only solution I found was set 25% scanlines, think on ZMZ as ZSnes interface but with the Snes9x or bsnes core.
