Interesting... the bios seems to be a japan bios because it says at boot time it is intended to be used in japan only.
So I deduce the jumpers has been changed to USA region in order to make such a game which checks the board region to works, while keeping the japan bios.
If I understand correctly, I may then reset the jumpers to the configuration described by the service manual. May I?
Can you please tell me the other jumpers setting meanings?

Furthermore, I understand sfish and sfish2 are cd-rom based games, so they require a cd-rom controller board.
If this video board has been intended to be used with one of those two games, there is a thing it is not clear to me:
According to the layout of this video board and according to the cd-rom controller picture I could see from system16.com, these two boards are not supposed to be used together in a tower configuration because they does not provide any CN type connectors on the component side, so they are mutual exclusive.
This makes me puzzled on the kind of game this board has been designed for.

Thank you.
