[Feature request]: Online Updater -> Update System Overrides

I propose a new entry: Online Updater -> Update System Overrides that works similar to Online Updater -> Cheats (for example. Metroid (USA).cht will be loaded with Metroid (USA).sfc).

Download the files

Online Updater -> Update Screen Resolution Game Settings it will create a directory called system_overrides and download setting files for individual games. Example files:

Super Mario All-Stars (USA).cfg
# Aspect ratio 8:7
aspect_ratio_index="22"

Metroid (USA).cfg
# Aspect ratio 8:7
aspect_ratio_index="22"

Chrono Trigger (USA).cfg
# Aspect ratio 4:3
aspect_ratio_index="0"

Mortal Kombat II (USA).cfg: 4:3
# Aspect ratio 4:3
aspect_ratio_index="0"

• Aspect ratio 4:3:[1] aspect_ratio_index="0"
• Aspect ratio 8:7: aspect_ratio_index="22"
• Each game has either 4:3 or "1:1 (8:7 DAR)" ratio - https://www.youtube.com/watch?v=ssluTgfkdlg&t=182s

1: aspect_ratio_index="0" will set the aspect ratio to 4:3 for both the GNU/Linux package, as well as the Flatpak package. "1:1 PAR (4:3 DAR)" for the retroarch GNU/Linux package = aspect_ratio_index = "20". "21 = 1:1 PAR (4:3 DAR) for Flatpak = aspect_ratio_index = "21"

Apply the settings

Like the cheat files, when the game file is loaded, it will look for a matching file name in aspect_ratio, and apply it to the screen resolution automatically.

Start by examining the Online Updater entries for Cheats and Update Screen Resolution Game Settings, along with the proposed system_overrides directory and matching .cfg files. Done means the updater downloads per-game override files and applies a matching file when the game loads, including the requested aspect-ratio settings.
