// shader 37040a485a29d54e
// This is based on the work of the following people:
// Clarity GFX
// Credit to Jamie for main coding.
// Credit to Kiri coding & Reshade logic.
// Credit to Cremtif for Help.
// Credit to Serfrost for preset values.
//
// The idea was to modify the Clarity GFX to keep the games as close as
// possible to the original, only adding lumasharpening (since Reshade has bugs with the inventory in full screen).
// Enjoy!
