Vampire and DrEggman have just released a program called PSPersonalize. This program allows the user to change the background image of your PSP. Please read all related info on this program before using it, this change will be permenant and you will need to reflash the original images (available below) to return to stock.
Here is what the creators had to say:
PSPersonalize is a PSP program that lets you replace the background images in your PSP menu. On the PSP, there are 12 backgrounds, one for every month. This program lets you replace any image you want with your own custom made images.
Read everything before taking any steps. We are not responsible for any damages in result of this application. Use at your own risk.
Hereís how it works:
There are 12 images in your PSP:
01.BMP - January
02.BMP - February
03.BMP - March
04.BMP - April
05.BMP - May
06.BMP - June
07.BMP - July
08.BMP - August
09.BMP - September
10.BMP - October
11.BMP - November
12.BMP Ė December
To insert your own images, simply put your own 24-bit BMP file in the root directory of your second memory stick. The filename should match the number of the month you want to replace. (Ex: I want to replace November so I would create a .BMP called 11.BMP and place it in my 2nd memory stick)
Do NOT put these images in any of the directories in your memory stick, the software wonít find them in this case.
Ok, now that we know how to replace the images, we have to know the rules. First, images canít be any larger than 150k. Thatís a resolution of about 300x170. The reason for this is that anything larger causes your PSP to not load icons properly. Second rule, these images must be 24bit. Do NOT use images that are 16bit or 8bit color.
