How to Create a PSP ROM for Emulator

JPCSP is an open-source java-based PSP emulator for the computer. PSP ROMs for this emulator are going to be ISO images for PSP games and Eboot files for homebrew applications. Creating a PSP game ISO works by changing the VSH menu settings, then directly downloading the image from a PSP running custom firmware to a computer. Placing the ISO into the "umdimages" folder of the JPCSP emulator folder allows the game to load when the game image is selected under the "File" menu.
