I started to work with this tut and found that it was written for an older version of PSP than I use.

There is good information in the tutorial, but it was difficult for me to follow.  Some excellent tips, tho.  I am always amazed at the difference in quality of the graphics we're using now and what was available during the PSP5 and 6 era... Seven was the turning point towards user friendly while 8 made a quantum leap - that began the era of misted tubes, larger images, cleaner designed graphics.  Even the image used in this tut is a rough cut of what we have available today.
