I have been using the PG file from Nems hello world to display graphics in all my programs and am having a hard time understanding what is happening inside the pg file. Can someone please show me some source that will simply write a square that is all one color to the screen and have its position change (to anything other then original) when X is pushed. I want to understand how to display simple colors, not bitmaps or anything just single colors. Try and make it as simple as possible.
I have looked at many source files, purchased books ( and was surprised to find a “Hacking the PSP” book which had basics for starting out), and spent hours just testing things. But I cannot figure this simple thing out. If someone could help me out that would be great.
