Things You'll Need
Instructions
Update the software you use to make ISO files, and convert these to Eboot files. Some popular examples include ImgBurn and PSX2PSP, the latest versions of which can be downloaded from "Resources."
Update the software your PSP uses to run Eboot files, as outdated software often does not run with the latest firmware or files created in newer versions of the Eboot conversion software. Visit your Eboot program's homepage to download the latest version of the software and install it on your PSP.
Clean your "Metal Gear Solid" game disc with methylated spirits and a lens or screen cleaning cloth. Any dirt or marks on the disc can create a corrupted ISO file, which in turn results in an Eboot file without all the data required to run on your PSP.
Insert the first "Metal Gear Solid" disc into the CD or DVD drive of your computer, and launch the updated version of the software you use to make ISO files. Choose "Make ISO" or "Rip Disc Image" from the "File" menu, and burn an updated ISO of the "Metal Gear Solid" disc image.
Launch your newly created "Metal Gear Solid" ISO file in a PlayStation emulator such as ePSXe or pSX to ensure the file works correctly. If so, convert the file to an Eboot using your updated conversion software. Transfer the newly created, working Eboot file to your PSP using your Eboot software.
