Hello World SourceCode Released (First PSP Homebrew Release)

Nem has released the sourcecode to his Hello World Homebrew Demo, he also said this:

<blockquote>
To build the code, I used ps2dev toolchain for PS2. There is no devtool for PSP yet. PS2 and PSP both uses MIPS cpu and there's some machine code compatibility. You can not use some PSP and/or C code features with PS2 devtool, but for testing it is enough. A lot of things to do.</blockquote>

to bad you can't use it on vr. 1.5.....I heard that there is a way to "downgrade" your PSP to a lower version so you can run Hello World and other future applications released

but still it only work on jap models
