Important Capcom CPS2 Announcement

Dear colleagues,

It is our pleasure to announce a very important milestone in arcade conservation, the successful reverse engineering of Capcom's CPS2 security programming. A major development giving full hardware control of this popular platform over to the community, and helping preservation by enabling the clean desuicide and restoration of any dead games without hardware modifications.
This achievement has been made possible thanks to the help, support and collaboration of many dedicated individuals who just like you have an altruistic passion about arcade games, their hardware, history and legacy. All the discoveries and results generated by this project will be soon shared publicly, free of charge.

Over the coming days the project will see a limited release to selected testers to help ensure maturity before the public disclosure happens.

Stay tuned to further details.

      Is that all....? That is simple wizardry compared to the multiple years it took to get half decent decryption. I knew you had it in you, and big thanks to all of the donators and researchers that help in this endeavor. CPS 3 will probably be a cake walk for you.

    That's great news, Eduardo.

    Out of curiosity, do you also happen to have any plans to do anything like this for all of those soundless Toaplan games, as well?

      The sound CPU chips have internal data that can't be dumped through normal means, which is necessary for Vimana, Ghox and Fire Shark/Same!Same!Same! to have playable music. Might be worth contacting tormod for detailed info.

      Thanks for the detail. I guess we need to gain visibility as to what's out there currently not emulable or desuicidable and define a prioritized roadmap.

      Eduardo, if you can, also take a look at the Nichibutsu arcade game "Tatakae! Big Fighter," which currently has an unemulated security chip that prevents the game from running in Mame.

      That's all? Really? No other hardware necessary like an EPROM programmer?

    3. Eduardo Cruz12 May 2016 at 08:12

      Correct, hardware stays unmodified.

      Hey Ed! Thanks so much for your hard work! We all appreciate it so much! I have a question. Will this revival process work with the "all in one" black boards?

    Hello.
    Thank you for providing the program.
    I am using Japanese black one board hyper Street Fighter II.You can now display rom check in your program.
    However, it freezes before checking the Q sound.
    ? Is there a difference between sf2j1dl_031222JAPAN and hsf2jdl_040202JAPAN?
