 <p><strong>Note:</strong>  RGBFix was previously released by me as a standalone program known as GBFix.  I have chosen to release it in the ASMotor package instead from now on. Its usage has changed a bit from that of GBFix for the sake of consistence with the other ASMotor tools. Being part of RGBDS means RGBFix’s
 distribution now follows the same rules as the rest of the ASMotor package. GBFix still follows its own rules.</p>
