Lunar 2 rom problem at disc 2. Game froze during duel between hiro and leo

I am having problem with the game Lunar 2 (Playstation 1 version) and wonder if anyone else has faced the same problem before.This occurs during disc 2 when I started fighting Leo (the white dragon knight) on the ship Destiny to get the white dragon aura (one vs one duel with Hiro). The game got stuck as soon as I started the fight with Leo.The system I am using to play the game is PSXeven and I obtained my rom from rombomb.com (the site has discontinued the download). I also tried using rom downloaded from romulation.net and the same problem occurred.If you have faced this problem before, please let me know how did u solve it. Your reply is much appreciated. Thanks

try using ePSXe, it is the most compatible of the PSX emulators.
