I confirm, but to be more precise, it's true for all versions of WPC-95 boards.
Indeed, some WPC-95 boards have hardware slightly different from the others (as for example, the prototype boards), but that does not change the operation.
Just replace the ROM and the associated SECURITY PIC.
The ASIC is the same for all boards, whether WPC-S or WPC-95. No need to replace it.
