Brigandine, Why is it not working properly.

I know this has been asked before but there haven't been a definite answer to this probelm yet.I recently downloaded Brigandine for the Playstation one. I use both pSX 1.13 and ePSXe 1.60. It loads normally but when I reach the Main Menu where you find the START; LOAD; and SOUND Option, it reverts back to the opening sequence. The only way that I can start the game is by rapidly pressing the X button to "catch" the START Option.Now it gets more complicated here. The game loads up fine but you won't be able to choose which character to play. Probably skips the character selection screen and chooses the default one AUTOMATICALLY.Does anyone know how to fix this? Or is it the ISO that is not working properly. Thanks in advance.

The ISO will be fine, it is a direct copy of the original disc. The problem will lie with your emulator configuration, and my first guess would be that one of the buttons on the 'controller' is mapped to a key on the keyboard which is continually sending a signal (stuck key)

Any idea how to work around it? I use the same configuration in my other games but it works fine. I use ASDF keys for the standard Playstation keys and the arrow keys.
