It's awesome that it has those settings. Sadly I couldn't try them out yet, because I can't get the emulator to work for some reason.
First I couldn't quite figure out ROM filenames (is BIOSROM.BIN right?), it would be better if there was a table with them somewhere in your wiki, because I don't think filenames for video ROMs are mentioned anywhere there.
But then I just get a black screen with access to settings, if I set it to show CPU speed, the speed changes sometimes, but that's all. I've tried various ROMs, tried to use internal ROMs, tried changing different settings, all the same. It's 64-bit version on W10. Either I miss something obvious, or something goes wrong in a weird way on my system.
Nice. At least makes me think that it's possible. Too bad I don't know much about shaders yet.
It's close, but not exactly there. Maybe it's hard to judge the ghosting thing by video though, seems too little 🤣 . There were also several types of those displays, and they've had it to a different extent. I mostly remember the mouse pointer having a trail, and it was Ok to play some DOS platformers on my notebook with greyscale screen, while on others picture in those could become seriously blurry. Well one of their main uses was something like MS Office 4 rather than games probably 😀 Notebooks like these
