I've been working for a while on a TSR for DOS, based on the AdvanceCAB code. What it does is intercept EGA (and VGA) graphic modes, 320x200, and apply the modeline we pass as parameter.
In case you want scanlines on a 31kHz CRT using a standard VGA card, this modeline should work. Everybody can tweak it to their own taste. What it basically does is double the Hz and disable doublescan, but any HZ from more or less 90hz and up will give real scanlines
device_video_modeline pc_31.5_vga_320x200 12.5876 320 348 366 382 200 212 226 232 -hsync -vsync # H 31469 [Hz], V 71.847 [Hz]
The effect is similar to running a 15kHz low resolution mode, but compatible with normal VGA monitors. Games look much closer to how they would on old RGB monitors or good quality trinitron TVs. The high HZ give more brigthness, like old screens or TV
Leaving some examples and the zip here. If somebody tests it, let me know. It's a beta I just compiled, I'll post a final version once I test it a bit more
Example of real scanlines on 31khz CRT for EGA games, they look amazing
