Is it possible to play Soul Blazer with snes9xw ?

[Peavy]

Hi every one... i have found Soul Blazer and i have decided to play with it ... i m using snes9xw to have a god emulation and to play my with joypad... but unfortunatly i have a problem with this rom (or with the emulator).... in fact, i m in the first level (Grass valley)... i have killed all monsters lairs, and when i come back to the village, i can't speak at all with thie different characters... for instance, the bridge keeper doens't talk to me.. and i can't talk with him.. in the house with a young girl and a moving chair, it's the same sing, i can't talk with 'em... is it a problem with my rom, with my emulator or my configuration ? i have another problem too, when i select items (swords, magics, items, etc..) instead of seeing an icon of the item, i have a square... this happens with snes9xw but not with znes...
can you help me ?
