People have been up in arms lately and there has been a lot of discussion about the demise of the PSP scene.  Today we have another release from Developer Avanaboy who is doing his part to put those ideas of a dead scene to rest.  Avanaboy has released P-Tester v2 which is a diagnostic tool for your PSP.  P-Tester lets you do a lot of testing on things such as the buttons as well as fixing pixels and several other useful functions.  Listed below is a message from Avanaboy on what P-Tester can do for your PSP.

"With P-TESTER you can :

*Test your PSP BUTTONS

*Test your PSP DISPLAY FOR STUCK PIXELS and FIX IT!!

*Test your PSP AUDIO SYSTEM

*Test your PSP BATTERY (since V1.5)

*Test your UMD Drive and your UMDs (since V2.0)

more features will be added soon ..

*Credits*

I'm releasing the source code too. I think that this might be useful
for those that want to learn psp programming basics, and for those that
just want to see how P-TESTER works."
