Backgrounds after the jump...
This first background is just a variant of an actual screenshot from the upcoming Chili Con Carnage. I really had fun with Total Overdose so I can't wait to get my hands on this. Plus, the game has missile riding ala Contra!
I just beat Gitaroo-Man Lives! a few days ago and I'm not sure the songs from it will ever leave my brain. I arranged official art from the game into a minimalist composition, but it works for Gitaroo. Put this as your background and then go buy the game if you haven't already.
Lastly there is the weekly non-video game related background and this week it comes from Afro Samurai. If you like anime even in the slightest I beg you to watch this show.
To put these as your PSP background, you can either save them on your computer and transfer them to your PSP, or if you're browsing this site on PSP, you can save them directly and when you're viewing the image on the PSP just hit the triangle button to bring up the image options and select "Set as Wallpaper".
