Script: Advanced Settings (GPI Case 2 Edition)

[EctoOne]

Use at your own Risk!

Here is another script I've written over the past few days.
It was only tested with a GPI Case 2 without Dock and has opinions especially for that case!
Also the method of deactivating Bluetooth and WiFi are only made for Pi 4s. I don't know if using this method would affect the older Pi versions or would be just ignored.

The main purpose is to be able to change certain things without the need for a Keyboard or SSH.

Features:

• Toggle BlueTooth / WiFi (CM4/Pi4 only)
• Switch Audio output [Stereo(Headphones) / Mono(Speaker)] (GPI Case 2 only)
• Toggle Ports Audio Fix
• Toggle EmulationStation Splash
• Toggle EmulationStation Exit option
• Reset EmulationStation UI to Full
• Toggle RetroArch Controller Notification
• Install GPI Case 2 SafeShutdown script (GPI Case 2 only)

Explanations:

• Toggle BlueTooth / WiFi (CM4/Pi4 only)
  Both modules are directly dis-/enabled via config.txt
• Switch Audio output
  The GPI Case 2 Speaker is not properly wired and will bypass default only output one channel. This option sets the output to Mono so that the Speaker is fully used.
• Toggle Ports Audio Fix
  I actually have no idea what the original problem was. I just noticed this post here: https://retropie.org.uk/forum/topic/29888/no-sound-in-ports/3?_=1659129304380
  I just added it because it was simple. Haven't tested it myself.
• Toggle EmulationStation Splash
  This will de-/activate the EmulationStation Splash Screen. The one with the ES logo and progress bar, not the Retropie Splash.
• Toggle EmulationStation Exit option
  This will hide/show the option to Exit EmulationStation from EmulationStations Power menu. I mean why do you want to exit to a terminal on a handheld!?
• Reset EmulationStation UI to Full
  This will reset EmulationStations UI mode from Kid/Kiosk to Full. The normal unlocked system never worked for me, that's why this option is here.
• Toggle RetroArch Controller Notification
  This will hide/show the (Xbox) Controller notification when starting a game. Again, seems like a useless feature on an handheld.
• Install GPI Case 2 SafeShutdown script (GPI Case 2 only)
  It does what it says. Like I said, the purpose is to not rely on a Keyboard or SSH.
  Important: It is still required to install the Display Patch first! And some sort Internet connection is obviously needed as well. The option just triggers the wget command from the RetroFlag site.
  Note: This option will only appear in the menu when the Shutdown script is not installed.

Installation/Usage:
Save the script with a Name without Spaces and the suffix .sh
Example:

AdvancedSettings.sh

And I suggest copying it into the retropiemenu folder. Then it will be available from the Retropie Menu in EmulationStation. If not, make sure to disable the Parse Gamelist option in EmulationStation.
The menu is hopefully self explaing and selecting an option will ask for confirmation.
Important: Most options require a reboot or at least a restart of EmulationStation, that's why there is also an option to reboot in the menu.

Feature Plans:

• Add an option to (partially) disable the Shutdown script. Because it also checks if the Dock is used, it is not possible to use the SD card in a different Pi. For some one like me, who's doesn't own the Dock, that might be interesting. But since I enjoy the handheld, it's not a priority right now.

I'm open for any other suggestions and feedback.

I get a lot of errors trying to run this script, syntax errors and unexpected tokens. We're just copying what you posted into a .sh file?
