Peter van Sebille has released SCap for the P800. This is a screen capture tool. It allows you to take screenshots with various hotkeys, and saving in different formats (gif, jpg, mbm).

Featurelist:[list][*]Save screens hots as 24-bits bmp, 8-bits bmp, gif or jpg. For jpg you can configure the image quality (and thus the file size). [*]You can configure screen shots to be stored on either the internal disk or the Memory Stick. [*]You can specify the base file name of the screen shot image files. SCap will append a unique number to the base filename. For example, the default base file name is screen and the default image type is jpg, so images are called screen.jpg, screen-1.jpg etc.[*]Select Camera button, Browser button, Power button or Jog dial select as the hotkey.[*]You can configure SCap to either automatically stop the capturing after you've taken a screenshot (and thus release the hotkey to its normal use) or to leave it on until you manually select Stop capture from the SCap menu. This is handy if you want to take several screen shots.[*]Visual feedback: If you enable visual feedback you get a small popup to say SCap is saving the image and a popup to say it is done. You can disable them which is usefull when taken screen shots of games such as EDoom or EMame as these popups will take these games out of their full screen mode. [*]Audible feedback: You may select an audio file to be played after the screen capture is fully completed. Audible and visual feedback are usefull because for example saving a screen shot as gif on the memory stick may take 10 seconds. In that period you cannot take another screen shot.[/list:u]
