Power Switch Disabled in Emulators?

Ok, so I updated my firmware to 2.0US to be able to use Firmware 2.0 Eboot Loader.

Works great, used it to load NesterJ, which also runs great. The problem is - how do I quit the emulator to go back to either the Eboot loader or Sony menu? If I have to power off completely to go to the regular Sony menu, I'm not able to do that either. The power slide/switch becomes disabled, and I have to completely take out the system battery pack in order to shut it off.

Any advice would be appreciated and thanks in advance.

Press and hold "L" + "R" + "Start", this will take you back to the EBoot menu, which you can then use to get back to the PSP Menu by pressing "Start".

You should still be able to turn the PSP off though, you need to hold the Power switch up for about ten seconds...it works on mine, I've got 2.00JP though.

Cheers,

the power off works on ALL emulators i tried.
that includes everyone but mame
just hold it up for, as mgfox said, about 10 seconds
