Calc help

press home

I highly doubt he hasnt done that.
If uve tried the home button then turn off ur psp.Alot of these things wont let u go back to the menu.
Tell me.If u have pressed the home button does it say: Please Wait...
and it will just stay like that?

you cant use the home button for this app. Thats one of the reasons why i deleted it, the second reason why ive deleted it is because its missing the decimal key, but anyways, to exit out of that, you would have to hold the power button for 5 seconds. Turning off your psp, then turn it back on.
