This is Remote Joy Lite for your PSP running on Custom Firmware 6.60ME. This will also work on 5.00, 5.50, 6.20, and 6.3X CFW's.
In order for this to work properly you need to install the drivers and i will show you step by step on how to do this.
Step 1: Take the Remote Joy Lite files and extract them to the desktop of your PC and then open the folder.
Step 2: Take your PSP and connect it into USB mode and make a folder on the Memory Stick (MS) root called "seplugins" (NO QUOTES). Open that folder and place the RemoteJoyLite.prx inside this folder.
Step 3: Create a vsh.txt a game.txt and a pops.txt file(s) in the seplugins folder and inside the game and vsh txt files write "mso:/seplugins/RemoteJoyLite.prx 1" (NO QUOTES) and exit and save. In the pops.txt write the same thing as in the game and vsh txt files but also add "flash0:/kd/usb.prx 1" (NO QUOTES) and exit and save.
Step 4: Disconnect the PSP from USB mode and take out the USB. now run the PSPdisp installer that i have for download. Say YES to everything and when you get to the screen that says to locate the GAME5XX folder hit cancel and continue saying YES to all.
Step 5: plugin the usb and the driver should install fine. If not run the PSPdisp again only this time with the USB plugged into the PSP with it on the XMB Screen.
Enjoy your PC screen view of your PSP :p
NOTE: if your display crashes, hit select on the XMB on the PSP and hit reset device, in the middle of the reset, unplug the USB but dont close PSPDisp or Remote Joy. once XMB boots back up, plug in the USB.
