A link to the rest of them.. Due to the AS upload size limit, which is 97.7kb, I will also add some megaupload links later which will include Shin Megami Tensei and Persona related PSP Wallpapers sized 480x272. For now, check this out:

And in regards to the megaupload links, some of the files are marked with (x) implying that its size is over the AS upload limit. I created a megaupload account and thought I should test it out to see if it works or not. Here is the test file:
Code Geass R2 (3.84mb) [41]
It contains 41 Code Geass PSP Wallpapers (480x272) including a few that I have been using all the time too. (^_^)
