Blood Bros. (Modular System)
As with most of the 'Modular System' setups, the hardware is heavily modified from the original
and consists of a multi-board stack in a cage, hence different driver.
For this game the Modular System cage contains 8 main boards and 1 sub board.
MOD-6/1 - MC68000P10, 6 ROMs, RAMs, 22.1184 MHz XTAL.
MOD 21/1(?) - 24 MHz XTAL.
MOD 1/2 - Sound board (Z80, 2xYM2203C). 2 8-dips banks + small sub board with OKI M5205.
MOD 51/1 - Sprite board, has logic + 4 empty ROM sockets. Sprite ROMs are actually on the below board.
MODULAR SYSTEM 2 - red sprite ROM board, 16 sprite ROMs populated (maximum 24 ROMs)
MOD 4/3 - Tilemap board, has logic + 4 27256 EPROMs, long thin sub-board (CAR-0484/1 SOLD) with no chips, just routing along one edge.
MOD 4/3 - Tilemap board, has logic + 4 tilemap ROMs, long thin sub-board (CAR-0484/1 SOLD) with no chips, just routing along one edge.
MOD 4/3 - Tilemap board, has logic + 4 tilemap ROMs, long thin sub-board (CAR-0484/1 SOLD) with no chips, just routing along one edge.
