Problem with PSX Backup of Multiple Disc Game

[nessmanjunior]

Hi i'm playing a backup copy of Lunar2: Eternal Blue for PSX. I've been booting it via a gameshark disc/swap method on an un-modded PSOne (the newer small, white version of PSX). My question is this...

I've played through the first disc of the game. At the end of the first disc it doesn't ask you to save before swapping discs. I am saved before the end of the first disc but when I play to the end of the first disc it says "please insert disc 2." I tried swapping disc 2 in using a swap method and booting disc2 from my previous save file and neither works. Is there anything I can do or did i just waste 15 hours playing through the first disc?
