The v2.0 software keeps on coming ( i foresee another section soon) and today Elz Development have released a Button Swapper for the PSP and also another Hello World proggy, heres the info:
Button Swapper (for 2.0)
This will swap your JP PSP 2.0 so you can use X (instead of O) as select.
Yet Another Hello World (for 2.0)
Yet another hello world for 2.0. Personaly I think this one is much better than the first one that came out, because this one got some small basic animations.
