I am currently trying to improve the graphics in one of my favorite SMS games and it already looks significantly better after I made better use of the 16 color palette in the sprites and backgrounds, but I could do a lot more if I could change a few colors in the palette.

Where/how do I find it?

It also would help me tremendously if I could extract the palette somehow for use with Tile Molester, because currently my method is "make screenshots, open in GIMP, paste RGB values into Tile Molester", which is a tedious task.
