PSP Backgrounds

Here are a few PSP backgrounds I made. You have to change the names around to get them to work though. I will probly make more, tell me if they are done wrong. Thanks.

MENUD.zip- contains a background of a cool dragon on old paper. Change name to MENU to get it work.

MENUB.zip- contains several backgrounds, you have to choose one to change, and do the same process as for the MENUD.zip. The colors inside are: Red, Green, Blue, and a Pink/Purple (for the ladies or guys that like a pinkish color).

I HOLD NO RESPONSIBILITY IF THIS RENDERS YOUR PSP USELESS

here are some pictures:

BTW, These are low quality compared to some other works I have done, I will put in some really cool ones soon.

ALSO, could someone answer my question: If i were to update from 1.5 to 1.51 and forget to remove my Background, would it freeze my psp forever? could I still change it back? Or would my PSP be useless?
