PSPdisp v0.1 - use your Playstation Portable as an additional monitor under Windows.

[wraggster]

News/release from JJS

Information
So what is this about? Well, it basically gives you an additional monitor with a 960x544 resolution (four times the area of the PSP display). There are four components working together, on Windows a display driver, an usb driver and the interface application which captures the screen, compresses it and sends it over USB to the PSP. On the PSP side there is an application that decompresses the frames and displays them. All settings are adjustable from the Windows side, the PSP really only acts as a passive display.

Requirements
PSP: Either slim or phat model running a custom firmware (tested on CFW 4.01 M33).

PC: Reasonably modern PC (Pentium 4 / Athlon64 or above) running a 32 Bit version of Windows XP. It may work under Windows 2000, but it is untested. 64 bit versions are not supported, as well as Windows Vista. I would like to provide a Vista version but it will probably never happen due to the changes in the display driver model regarding multi-monitor support.

Installation
Windows application, drivers, etc.

Download the installer below and execute it.
When it comes to the display driver installation, Windows will warn you that the driver is unsigned, let the setup program install it anyway.
After setup has finished, open your display settings and enable the new monitor then move it to the position you like.
Connect your PSP and copy the files from the "psp" folder in the installation directory to the memory stick.

Compiling the source
The whole project needs three different compilers / IDEs, fortunately all of them are available for free on the net. Note that the setup process for them will take a while and is rather involved.

The display driver needs the Microsoft WDK (Windows Driver Kit).

Building the Windows application requires Borland Turbo Delphi.

The PSPSDK (PSP toolchain) is needed for compiling the Playstation Portable application. I use the PSPSDK for Windows.

Possible enhancements
There are quite a lot actually:

Make an installer that can create hardware nodes and therefore install the non-plug-and-play display driver (maybe from the devcon source)
Use information from the display driver to only redraw "invalidated" parts of the screen.
Reduce CPU usage by using other compression methods (or do parts of the compression on the GPU).
Make the application survive the unplugging of the PSP while the display function is enabled (currently hangs the application both on Windows and the PSP).

Demo video
A short video demonstration is available on Youtube and embedded below. It shows the relative smoothness of the Winamp visualisation and the transparent integration into windows. Also features switching between stretched drawing and mouse following mode.

Cool, going to try it out.

Thats pretty sweet. Im not sure how useful it will be though.

Pretty good, but this was done about a year ago, and also you could move the mouse with the PSP wirelessly. But this resolution is way better, still good tho

[brasssmunky]

the other thing wasnt very good
but it was wifi
it was slow, and buggy

[Uberman]

That's very slick, JJS. Way to go! :thumbup:

Not sure what I'd use it for, but someone will think of something cool, I'm sure.

So... Half-life 2 on PSP!

Nah, I'm not that excited, but might be cool to check out what can and can't execute, later on

First off i'd like to say, what a wonderful app you created. very well done. interface is simple and great options.

There is a few things i'd like to suggest for future releases.

1. As said above, WiFi is a must to have to remotely view your computer desktop

2. ability to right click (Edit: i found my windows overlay program called windows blinds, made the menu's not appear. right click does indeed work!)

3. use analog stick to move mouse with abiity to map psp controls to mouse as well. so like X = left click, O = right click, sholder buttons = alt tab for moving between programs fast
