GroovyArcade front end resolution & Sound Blaster Audigy 1

[maa]

Hello guys! I'm new here and also new into GroovyArcade and for now I like it!

I've recently build a retro pc and installed GroovyArcade, the last release (2024.7) and it's working very very well on my old pc, connected on a Sony G500 21' CRT monitor.
The monitor is connected using the DVI-I of my gpu (I don't know if it's important for my question but, just in case, you have the info).

My only problem with that actual setup is that the resolution of the front end is probably the maximum my monitor can go (2048x1536) and I wanted to know if it's possible to reduce that resolution? (photo in attach).
When I launch a game, it switch to the native resolution of the game and it's perfect, but if there is a way to set the resolution of the frond end, and if someone can tell me how to do it, it can be fantastic! :)

When I open the desktop, the first time it also was the maximum resolution but you can change it in monitor settings of lxde.

My actual setup is: (I don't know if it's important but like this you have all my specs)

cpu: Intel i7 2600
gpu: Nvidia GeForce 760GTX
ram: 8go
monitor: Sony CPD-G500 21'

Small edit, I also wanted to know if there is some support for the Sound Blaster Live Audigy 1 because it's detected in the hardware specs but seems to be not claimed (I don't know what to do with that)
So it's actually working with the sound card of the motherboard.
Is there anything or any driver to install? I've found some drivers but I don't know what to do with them (linux is very new to me, but I learn quickly)

Thanks :)

GA is probably getting that resolution from your monitor's edid. So if you want to set a different one for the frontend, I think the most direct method is to create an edid binary that overrides you monitor's edid. Or use one from the included ones, e.g. arcade_31 for 640x480, adding this in the kernel boot line: video=DVI-I-1:e drm.edid_firmware=DVI-I-1:edid/arcade_31.bin

Regarding the sound card, you need to select the correct sound device from in audio setup menu.
