PSP Zones has posted the release of PSPShot v0.1 by Tsukasa. PSPShot is a homebrew application that allows you to take a screenshot of your PSP at any time.
Please remember this is the FIRST release of this app so it is still a bit buggy and can cause trange lines to display on screenshots if the background on the PSP screen is moving too fast
The Controls are as follows:
Start: Starts the system menu in “screenshot mode”
Select: Starts the insertet UMD in “screenshot mode”
L: Enables normal movement
R: Makes a screenshot
L+R: Exit the program
You can download PSPShot v0.1 here.
Note: According to the Read Me, this program only works with firmware 1.50
