- Correct ROM labels for: ssonicbr, ooparts, headonch
- Does ooparts actually use upd samples? PCB has the same rom as tfrceac
- Is the joystick hack for ooparts unofficial, or done by Sega for location test?
- Puyo Puyo 2 VS link capabilities
The "Print Club" boards used by Atlus are variants of the C2 board. Important differences:
- XL2 is 52.867MHz, instead of 53.693MHz.
- The 315-5242 DAC is on a riser board called 837-7694. It has two 74LS273 ICs
between the original DAC location and its spot on the riser.
- There is a daughterboard attached to CN4, which is also populated in the reverse
orientation compared to a normal C2 with CN4 populated (in terms of the polarizing
key orientation).
- The daughterboard is labeled 839-0805, and contains a TC82C55AM IO control IC,
as well as some 74 series glue logic and passives. This board talks to other
devices used in the print club machine. This board has a 1990 stamp on it, which
dates it much earlier than the known Atlus Print Club games.
- There is a larger board responsible for RGB multiplexing and encoding, named
837-10507-01. It takes RGB in from both the C2 PCB and (presumably) the camera.
ICs of note include Sony V7040, Sony CXA1688M, SBX1744-01 (submodule).
It has two sets of RCA jacks, likely for NTSC-compatible camera input.
- The wiring harness has power connections and monitor connections similar to or
directly compatible with that of a Sega New Astro City monitor and power supply.
With XL2 replaced, the DAC brought down from the riser, CN4 rotated 180 degrees, and
the I/O daughterboard disconnected, it becomes a normal C2 PCB.
Notes regarding Puyo Puyo 2's link capabilities (Mike Moffitt 2024-05-24):
Puyo Puyo 2 boards often (but not always) have CN4 populated. There exists a daughterboard
that can be installed to allow two PCBs to be networked for a four player mode. A video has
been shown that confirms this functionality works, but supposedly this peripheral was not
released by Compile/Sega and thus never reached mass production. A reproduction exists but
is not for sale, and documentation of its functionality does not yet exist.
From what I can tell, the daughtercard at CN4 is mapped into odd bytes at $880100. I think
it is a small amount of RAM, shared with a Z80 processor or compatible microcontroller.
Puyo Puyo 2 has a task that runs periodically to assess the status of the versus network.
Its initialization looks like this as far as I can tell at the time of writing:
CommMessage := $880101
CommStatus := $88010F
CommCommand := $880111
CommControl := $880131
- Write $01 to CommControl, then write $00 six frames later (reset message?)
- Sleep for 120 frames (two seconds)
- Go back to top if the current frame count is not a multiple of 4...
- Write $FC to CommCommand (signature request)
- Look for a signature string "PUYO2Z80" from CommMessage (on odd bytes)
If the signature has a mismatch, the process begins from the top.
From this point the test menu will show that the comm board status is OK.
- Write $FD to CommCommand (CRC request)
If the result is zero, the test menu will clear the CRC error and proceed.
- Now the string "PUYO268K" is written out to CommMessage (on odd bytes), across
eight frames (one char per frame). Each write looks like this:
* Write $FF to CommCommand
* Write $01 to CommStatus
* Write $FD to CommCommand
* Write the character to CommMessage + (2 * index)
* Increment index, yield for one frame
- Once again check that the current frame count is a multiple of 4, and if not,
abort and go to the top of this process.
- Command $FD is written once more (CRC request?) and we expect to see $FF in all
eight characters of CommMessage
- The test routine marks the board as good, but not yet the loop test.
- Yield for one frame.
- Command $FE is written to CommCommand, and it's expected that CommMessage's first
byte is $00, otherwise the process rests.
- With the $00 response identified, the status has the loop OK bit set, and the link
status is entirely satisfactory. The test menu then proceeds to allow TX/RX.
- The link task accepts a new routine pointer and stores it in its TCB to handle comms.
This task runs in the background, doing this init periodically if a link isn't established.
The test menu only exposes the current status but doesn't do anything to affect it, aside
from letting the user manually reset the link status.
The string would imply that there should be a Z80 system on the board, and some shared RAM.
The 68000 side does not write a program of any sort to this IO area, so it's unlikely the
Z80 software is packed into the C2 code anywhere (and I cannot find the PUYO2Z80 string).
How the TX/RX works is not yet understood.
Thanks: (in no particular order) to any MameDev that helped me out .. (OG, Mish etc.)
