I followed this guide: http://freemcboot.psx-scene.com/swap.php I have an old fat PS2 and I got a copy of 007 Agent Under Fire. I get the game image, use apache to change the driving.elf size to 915196 (dec) and replace it with the one I renamed to driving.elf. I burn this ISO to a verbatim DVD-R at 2x speed. I beat the first mission and then I save my game. I swap the discs in the main menu, navigate to the second mission, start it, and I wait forever for it to boot into uLE. Never does. Just a black screen of false hope. My memory card's capacity is 8 MB and has 4 MB available.
