PSP Color shader to fix inaccurate pallet colors outputted by PPSSPP.
Color correction: set the value at 1.10 for both contrast and gamma for high contrast fidelity
I think it's time to go back and do some PSP RPG marathon, starting with Final Fantasy Type-0, the game you see on those two screenshots
It basically corrects the miscoloration and oversaturated hues of PSP games displayed on modern screens.
if you don't have it on, you are losing a lot of details
The combination of Zfast LCD shader with gba color is mind blowing
Adjusting and editing on screen touch controls on the app is not straight forward like on every app, and requires a lot of searching and learning and Google asking, however, once you get the hang of it, you will find out that the controls on Retroach are the most responsive controls out of any app, you can easily pull off motion inputs and you will never put your finger on a blank spot by mistake whenever you try to touch a specific button.
still, an implemented in app pad editor or a standalone Retropad app that let you drag buttons around would be great addition
