240p requires a custom build of the mister binary because they have pixel clocks around 6mhz and mister doesn't allow pizel clocks under 20mhz by default. With a custom mister build, 240p modes work fine. I use one for gameboy on my crt tv.

I haven't made an interlaced modeline for mister before. Can interlaced modes be given through mister.ini?

Is there still the 6mhz limit in default MiSTer binary? Where to find the custom binary? I am hoping to create several custom resolutions for using in a 15khz monitor for the menu core to enable screen-saver and for other cores that doesn't display in 15khz like GameBoy and Apple II.
Is there a calculator or something to create those modes? For example I would need 640x240@60hz and 320x240@60hz

In order to have menu core at 640x240@60hz I created a custom resolution, I paste here what you have to append to mister.ini:
[Menu]
video_mode=640,8,58,78,240,1,3,18,12324
vga_scaler=1
vsync_adjust=2
vscale_mode=0
