Graphics for the H8-based games are stored in either four socketed DIP28 8-bit EPROMs, two socketed DIP40 16-bit EPROMs or one
|
||||
surface-mounted SSOP70 32-bit ROM. Later H8-based PCBs have a custom QFP device labeled "SG 003" instead of the off-the-shelf
|
||||
RAMDAC.

To do:
|
||||
|
||||
- Add sound to SS9804/SS9904 games.

|
||||
command is issued, and only the first 8 bits returned are examined to determine whether they match the expected device code (0x14).
|
||||
If this test passes, the EEPROM contents are recalled and the first 64 bits are read out. These 64 bits are then unscrambled using
|
||||
a permutation table common to all games. The second and final protection check compares byte 6 in the unscrambled data buffer
|
||||
against a game-specific ID code. This byte is composed of EEPROM bits 22 (MSB), 27, 52, 50, 42, 9, 38 and 35 (LSB).
|
||||
|
||||
It is unknown where this protection EEPROM exists on any Subsino PCB (if it isn't an external dongle), though the IC package is
|
||||
known to be quite small. (The iButton version, DS1971, is another possibility.)

against a game-specific ID code. This byte is composed of EEPROM bits 22 (MSB), 27, 52, 50, 42, 9, 38 and 35 (LSB). This EEPROM
|

comes in a small TO-92 package which is very difficult to spot on PCB photos, though it appears to be typically positioned near
|

one of the edge connectors.
|

|
||||
Timings in the Z180-based and H8-based games consistently fail to meet 1-Wire specifications. In the case of the H8-based games,
|
||||
this likely has to do with CPU clocks and emulated cycle timings being both too fast. There may also be wait states programmed
