There is a software, but again, it's useless because the textures will not have the same filenames as the texture dumps. So if you extract textures from the .iso and put them in replacements folder, none of them would load without the filenames...
You can extract images on some games, but they are missing the names to be used as replacements. so the only way is to finish the game, but cheats help alot to finish sooner. i sometimes rip images from pc versions if they are of higher quality...
