Zettablade has just released his uber useful homebrew app for the PSP, vLib. vLib, also known as the Velocity library, is a general purpose library which contains all the basic stuff you'll need in making a simple 2D game.

You'll also be glad to know that he's releasing vLib under GNU General Public License, so anyone who's interested on working on it is welcome to do so. As long as you go by the rules, of course. More info about this and other essential details can be found in the readme, so we don't even need to stress how important it is that you check out the readme file.

Here are the current features you'll find in vLib:

* Loads PNG images
* Load image into ram and vram
* auto-swizzles images upon loading (makes for a much faster blit)
* Draw and unload images
* Use a linear filter on an image (to smooth it)
* Custom controller input structure
* Most basic functions needed for initlizing the gu and drawing, as well as vsync and double buffering
* A function that displays the current fps and the current available memory in the upper-left corner of the screen.
* Can also display any extra info you would like.
* Load custom mdl file.
* Display models
* Primitive display list
* 3rd person camera

But before you get all excited in tinkering with this app, you should know that it requires the following (and we quote): SDK installed from toolchain (no preinstalled crap), libpng, zlib, and libjpeg. Got that? Good. Again, check out the readme, alrighty?
