P-TESTER - PSP DiAGNOSTiC TOOL
I've developed this diagnostic tool called P-TESTER for PSP, using PSPSDK..
I'll release the source code within the next 24 hours..
From readme:
*What is P-Tester?*
P-TESTER is a diagnostic tool for sony PSP.
*Installation*
Copy P-TESTER folder in ms0:/psp/game/
and then boot from xmb.
*Notes*
With P-TESTER you can :
*Test your PSP BUTTONS
*Test your PSP DISPLAY FOR STUCK PIXELS and FIX IT!!
*Test your PSP AUDIO SYSTEM
more features will be added soon ..
*Credits*
I'm releasing the source code too. I think that this might be usefull
for those that want to learn psp programming basics, and for those that
just want to see how P-TESTER works.
If you find a bug, or if you have any idea, please contact me!
