im sure my question was already anwsered but in the sticky its like 20 pages long i sat and looked but i gave up but here is my problem annyways ok i used PSPpersonalize and i loaded 12 images they work sortof some times if i change the month my image just goes all white and when i have an image working i can see the old psp background therebehind my image do that stupid wave it does any help on how to get ride of this?
In the guide there is a FAQ section, this should answer your first question.
Second, the wavey lines are part of the PSP's OS itself, you can not get rid of them.
after you switch months and the screen turns to all white, press the X button twice. This "bug" of sorts does not happen when the PSP changes months on its own. FrozenIpaq is correct as well, the answer is in the guide.
