Thank you so much for your help, Zombeaver ?!
I'm relieved because my intention was actually to "play around" ?. Well... to be honest, I already tried various presets and play around. But by doing so, I encountered some issue with manu of your presets and if it's ok with you, I'd to share that here (let me know if it's not the right place to do it). By trying to use many of your presets, each time RetroArch indicate that it failed to load them. So I took a look in the log console and those kind errors are displayed (for many of your presets) :

If I'm the only one getting those errors, the problem could be on my side then?... But I believe I correctly installed the shaders as shown below :
Would you have an idea about the source of this kind of issue, please ?
Thank you in advance !
