This is a real simple way to make your PSP playable on your TV, just follow the steps.
A video camera
Cords to connect your video camera to your TV
External controller for the PSP (optional)
Step 1: Put your video camera up on a dresser or table and connect it to your TV so your TV shows what the camera sees.
Step 2: Now place your PSP far across from the camera at the same hieght as it on another table, chair, bed, ect. and zoom the camera in so that all the TV shows is the PSP screen ( there many be space below and above the screen of you don't have a widescreen TV, but fit the whole screen on the TV)
Step 3: If you want you can attach an external controller to it which makes it alot easier to play, but otherwise it kinda sucks. I'm looking for an external controller and if someone knows where to find one feel free to post a link.
Here are some gameplay screenshots and videos:
