CPS1 Project Update

Programmer code
The code needed by the programmer has been made available on the following github account: https://github.com/ArcadeHacker

Each folder contains the base code for the systems supported by the programmer. Before using your programmer make sure you run the right code for the target system to desuicide. 


Supported systems*
Pre-CPS Kabuki Z80 CPU based boards (Capcom and Mitchell)

CPS1 & 1.5 QSound titles 

*Important: make sure you read the known issues block further below.


Building your own programmer
The base of the programmer consists of two Arduino pieces:


I/O with the target arcade pcb happens via the 7 pins found just above of the lcd shield right side, look at the Kabuki pdf instructions for further visual reference, tap ground feed from the ICSP connectorhttps://github.com/ArcadeHacker/ArcadeHacker_Kabuki/blob/master/kabuki-instructions.pdf


Updating your programmer
In order to update your programmer or switch target systems you need to download the code using the Github mentioned above, look for the .ino files. Once you have downloaded the code just plug your programmer via USB to your computer and upload the right .ino code file using the Arduino IDE. If you don't have the Arduino IDE please download it from the following link:https://www.arduino.cc/en/Main/Software

Once updated just follow the programmer on-screen instructions.


Programming instructions

CPS1 & CPS1.5:
There's no documented guide yet (pending task), please follow these steps:

CPS 1 C board pinout as follows:
Connect programmer pin 3 to CNB pin 61
Connect programmer pin 4 to CNB pin 62
Connect programmer pin 5 to CNA pin 19
Connect programmer pin 6 to CNA pin 20

Please watch this video to see the whole process in action:

IMPORTANT: The programmer does not have enough power to drive the C
board. Watch the video to learn how to piggyback power from the game
motherboard.


Known issues [March 7th 2016 all issues fixed]
The following Pre-CPS titles have been reported not to work or have issues with the desuicider: Super Pang, Poker Ladies
Current behavior: Games start but freeze.

The following CPS1/1.5 titles have been reported not to work or have issues with the desuicider:  Cadillacs & Dinosaurs, Captain Commando, King of Dragons, Quiz & Dragons
Current behavior: Some graphic layers are missing.

Note: Thanks to Corrado, Tormod, Sylvain, and Bill D. for their patience and assistance.


Next steps
I'm currently converting one of my CPS1.5 titles into Cadillacs & Dinosaurs to be able to research the issue common to all four CPS1/1.5 games listed above. ETA before I start the research is 2 weeks from now.


Project pending tasks

  8. Hello Edoardo, I've tried all the evening to work on a king of dragon but after I send the command I see unlocking and then many strange characters

    I check the connection many times, also sent some images to Corrado Tomaselli and he says that everything is correct. I tried to take power from pc and then from a phone charger usb.

    what can I try?

    thanks

    Aldo

  13. Thank you for making this amazing product.
    I have a question

    I want to desuicide 'Knights of round japan ver'
    Is the Japanese version also desuicide possible?

  14. Thank you for your hard work on this! I am attempting to desuicide a Three Wonders. Upon choosing Three Wonders (or any game) on the LCD shield it first says "unlocking..." and then the LCD shield displays a series of underscores, question marks, and left arrows (e.g. _?<-_<-??)
    What am I doing wrong?

  16. Actually, just figured out that you must use an older version of Arduino IDE (I used 1.6.4) instead of 1.8.x and now no more weird characters! However, during programming it doesn't show the bit (byte?) count up to 144 like on your YouTube video. It just goes from "unlocking..." to "programming cps1" to "done". And doesn't seem to actually program it as the game still won't start.

  17. Hi Eduardo,

    As always, thank you for these great tools. I have desuicided a couple CPS-1 boards and a pre-CPS1 board. Never a problem, the process always goes well. I put together a simple visual aid to help folks like me that are more of visual learners, for the CPS1 desuicide process. I find that whenever I do one, I have to backtrack through your video, the written description here, and basically piece together what wires go where. Maybe I'm just slow, but possibly this would be helpful to others. Feel free to add it to your blog if you think it would be of any value. https://klovimg.com/image/PYxkg Thanks again!

  18. Thank you very much for sharing all the valuable information and your incredible tool.
    For me, there is still one (minor) question open: Is there a 18-byte dataset, that will turn a CPS-C-Board with volatile memory (e.g. 3 wonders) into a standard C-board (e.g. SF2CE)?
    Thanks in Advance for your answer.

  19. I have a Adafruit i2c 16x2 RGB LCD with Keys (https://www.adafruit.com/product/715 + https://www.adafruit.com/product/398). Will that work in place of the one you used? I'm trying to de-suicide a King of Dragons.

  20. Hi
    I have a Final Fight PCB with a faulty C-Board. I'd like to replace it with a B-21 C-Board, but is this possible to set the B-21 custom chip up to work with Final Fight (using battery and Adruino programmer)? I'm pretty desperate with this faulty game.

    Besides, is there any way to contact you directly?

    Best regards, thanks for your great work
