Not really.
Except several slight differences between the NA and JP version. For example, the Symbols N in Nikki's room and on Termina's dock are all S in the JP version, 'The Dragon's Tail' is 'Bar Dragon', 'LISA'S SHOP' is 'YURIS SHOP' and other minor differences if you'd like to explore...
OK, just noticed my previous background rip of the Dead Sea library from the emulator didn't have the semi-transparent (ghostly) effect for the Viper Manor residents. Though it is harder to recognize who is who.
