This requires custom firmware on your PSP and this guide assumes you already have a modern custom FW.
Screenshots taken with RemoteJoy
RemoteJoy allows you to play your PSP on your PC — you can take screenshots and record video, use PC controllers, etc. Personally, I use it more for screenshots/video/live streaming because there’s a few milliseconds of input delay.
Prepare your PC:
-download/install USB Type B drivers
-download/run RemoteJoy GUI
Prepare your PSP:
-in the Remote Joy zip, there’s a .prx file — copy that to your /seplugins/ folder on your PSP
-open game.txt with notepad and add the line: ms0:/seplugins/RemoteJoyLite.prx
-boot into recover mode on your PSP (turn completely off, hold R while turning it on), go to plugins, enable RemoteJoy
Then, while RemoteJoy is running and your PSP is connected to your PC via USB, launch a game on the PSP. You should get an ‘install new hardware’ dialog — after finishing that, you should see your PSP video in the Remote Joy window.
