So I'm using ePSXe and the rom supplied at coolrom works fine, apart from one issue.

Those of you familiar with the game will know that one of the charactars has a gun, which he uses for special attacks, instead of abilities using mana. This requires ammunition.
Ammunition can be restored either with a fairly rare item or visiting a guy in town, who will give you a price and then you're supposed to say "yes" or "no".
However, with my issue, the box in which yes and no would be displayed is empty and the game stops responding.

Sorry if I haven't provided enough information, I'm new here.
