Why increase saturation?
The Retroid Pocket 3/3+/Flip benefits from an already very good LCD screen, and boosting the saturation can surprisingly make it much appear much more like an OLED screen.
NOTE: Boosting the saturation too high can actually make some things more difficult to discern, such as light shading or subtle textures. Fortunately the process is reversible and you can tweak and test until you find a level that you're happy with. In the Retro Game Corps video, Russ mentions that pushing all the way up to 160% makes it most OLED-like, but I personally found I was much happier around the 120-130% range. Just enough to pop without losing too many subtle details.
Tutorial
Setup
- Download these script files and add them to the Downloads folder of your device.
Backup your default saturation levels
This is so you can easily revert any changes you make if you don't like how things turn out.
- Go to Settings > Handheld settings > Advanced > Run script as root.
- Select "getDefaultSaturationValue.sh" and run.
- Verify that the file was made by checking in your Downloads folder for a file called "DefaultSaturation.txt".
Change your saturation level
- Go to Settings > Handheld settings > Advanced > Run script as root.
- Choose the .sh file that you wish to try out and run it
- Reboot your device to apply the changes.
Making a custom saturation level
- Duplicate one of the .sh files and open to modify it.
- Change the number at the end to reflect what value you want to try (such as changing 1.7 to 1.3).
- Change the name of the file to reflect that value. (setSaturation_1.3.sh)
- Run the script same as above.
There you go. It's a very fast and simple process, and a nice way to give your Retroid device a little pizzazz if you want.
