Did you try putting disc one back in and attempting to provress the game off that? Used to do it with FFVII and VIII. Other than that, you'd be better off trying it on a ps3 or just a ps1, or try using an emulator program on pc to pass the part your having troubles with, though it would require a device to upload your memory card file to your pc and then back again. I'm telling you this because LoD is fairly rare nowadays, and I can bet money that even if someone had a copy, getting a loan is incredibly unlikely.
Last option is drop 250 on a ps3, and download it off psn or run your discs on it. You're also gonna need a memory card converter, which are rare.
