Found something else neat, even if it's not exclusive to Paint Shop Pro. It's stupid-easy to paste things from the clipboard into YYCHR. For NES games, I found that if I select the same four colors I have chosen for the viewing palette, make my tiles or sprites, then invert the colors, I can paste the inverted image into the cell(s), and they flip back to the appropriate values automatically. Another plus of PSP is that you can easily set the grid to 8x8, making it even easier to manipulate tiles and the like, from a larger image. Have a picture you want to stick into a game quickly, like a new title, or cinema image? Once you figure out which tiles go where, you can make your full image in four-color mode, then copy and paste 8x8 cells rapidly into the ROM. Really sped up my sprite editing for my Metal Gear project.
