The NEW Build Your Own Arcade Controls

Hello everybody,
I am fairly new in the world of arcade emulation and I'm probably missing something obvious.
I use GroovyArcade on my pc to which I connected a DisplayPort LCD monitor and a CRT TV (configured as an NTSC TV), my goal is to play with the NES (U) roms having an image and frequency identical to what I would have with a NES NTSC plugged in. The point is that I just can't figure out how to get this fidelity by starting the rom from AdvanceMENU Plus (and therefore from NESTopia) or from Attract Mode (and therefore from mednafen).
From what I understand I just need to set the resolution I want on Xorg and the frontend through switchres will try to start the emulator at that resolution, is that correct? I have tried several resolutions but I never get the result I want, for example the scanlines are always missing. Right now my intent is to play a specific NES game but this problem is general, for example a PS1 NTSC game (setting a resolution of 320x240 @ 60hz on Xorg) does not have the same image with scanlines that I would have on my real PS1 with the same NTSC game.
Thank you

Nobody? What would be the practice? What resolution should I set on Xorg to have an image faithful to a NES NTSC? Or a PS1 NTSC?

Hi robsmashed,
I'm no expert of Groovyarcade, but game resolution is a matter of emulator. So, you should probably have a look on emulator configuration.
NES games uses 256x240 video mode, so you'd better use a 256 multiply width (256x240, 512x240, etc..).

Hmm, switchres switches to the resolution I set for Xorg, so the emulator starts with that resolution. Best I can do in emulator settings is selecting 1:1 for aspect ratio and scaling.

A few things to know :
- it all depends on the emulator you use. Mame can émulateur the nes I guess, so there would be no particular setting to do, just configure the frontend
- don't think "i need to set this resolution to play this system". This depends on several cases -> does the emulator natively handle switchres ? (Most chances are no unless you use mame as of today) ? Does this console have in game resolutions switches ? That's the case of psx. If my emulator can't switch to a good resolution, how to do that then ? Easy : launch the emulator using switchres. Switchres will set the required resolution then launch the emulator.
