I have a "screen" in my rpg where you can increase some skills and somesuch, which I've created using a map and four 400x400 pixel tiles to make up the interface background. (Buttons are stamp-based, and controlled via events.) My problem is that, while my buttons show up okay, the "ground" tiles are all garbled with colors and lines crud all over the screen. The game still works fine, but this garbledness is a problem. I've tried both the png and pict formats, making the names simpler - everything. In short, these tiles should work fine. My stamps work, so I don't think ignorance of proper settings in Photoshop is the explanation here.
The autotrophic organisms are decidedly more verdent when located on an adjacent surface.
