PSP Windows v1 (Lua)

Slasher (No Official Website) has released what looks like a windows for PSP, it actually does look like Windows XP on boot up, heres the scoop from the readme:

This is basically a windows shell, inspired by fluff.( you pwn fluff ) It's in its very early stage considering I made this in only the last couple of days. I hope to include more features , and eventually transfer it over to C++ for even more functionality. Right now it only includes one game made by myself called TehPwn, but I hope to add more games. I have added the ability to change the speed of the cursors falling and the speed of the line moving in teh pwn.

Holy crap, that looks awesome on my psp, I hope he expands on this because its already lookin cool.

well from the scenes of microsoft greedy bastards tehy will most likely sue teh person who is making this so i would recommend changing the name atleast or making linux version rather then windows

How can one code this? Isn't it not open source?
