It's been a while and i still don't have a PSP but with the help of some friends (letting me borrow their psp or testing for me) i finally got around to getting all the bugs out of NPaint and adding a few more features.

Changelog:

-added a feature that allows you to change the theme color for the border.(R,G,B)
-fixed music volume.
-fixed bug causing brush to move back to the top left corner after changing color.
-fixed ALL menu bugs by completely recoding the entire menu.
-removed the random bars in the main menu.
-reduced sizes of menu images by cutting out the parts needed instead of loading an image the size of the screen.
-menu screens should appear faster now that it doesn't randomly load constantly when choosing a new option. instead all images are loaded at the beginning increasing the loading time by a few seconds.
-added an error message warning you when you try to load an image and you have no image saved.
-added support for 3.71+ for Slim and Original PSP's.
