/***************************************************************************
The current ROM set is strange because two ROMs overlap two others replacing
the program.
It's definitely a Kaneko boardset, but it could very well be they converted
some other game to run Gals Panic, because there's some ROMs piggybacked
on top of each other and some ROMs on a daughterboard plugged into smaller
sized ROM sockets. It's not a pirate version. The piggybacked ROMs even have
Kaneko stickers. The silkscreen on the board says PAMERA-4.
There is at least another version of the Gals Panic board. It's single board,
so no daughterboard. There are only 4 IC's socketed, the rest is soldered to
the board, and no piggybacked ROMs. Board number is MDK 321 V-0 EXPRO-02
