I present you my Homebrew called PsPixel, it's the second version (the first one was published on Pspgen.com on december 2009.)
Of course if I propose the version 2 today it is because I made many modifications. Now let me present you PsPixel :
This Homebrew permit you to make your own pixel art on your PSP.
You can :
-Select your language, french, english or spanish
-Change the color, with the selection of the RGB (red, green, blue)
-Save a second color, so you can switch between these two colors quickly
-Look at a "Color page", you have the most used colors with the RGB
-Change a color with another in your pixel art, the color which will change is the "Second color" and the color which will be print is the "First color"
-Save your file in picture/pspixel v2.0 in .png, the directory will be created, you can save as many files as you want. You can save it with pixels 1/1 or 4/4, if you select 1/1, you have to wait 10 second, because the pixture need time to get the good size (see screenshots for more details)
-Select a file to load in picture/pspixel v2.0 (only if it's a .png or .jpg), preview the picture before load it
-Change the size of your "pen", 8/8 or 4/4
-Copy a color in the screen, it will be your new "Second color"
-When you want to load an image you can delet it with triangle. A question will ask you if you realy want to delet it or not. It works when you see the image before load it.

Hope you will enjoy !
NEW VERSION : See the 2 last Screenshots : You can select 1/1 pixel or 4/4 when you save your picture. 1/1 will unzoom your picture. => It makes 10 seconds, you have to wait and the picture will get the good size.
If you want, you can also load your picture into 1/1 and save it into 1/1 again, it will make your picture smaller and smaller
