    • InfiniKey-CPS1

      It's happening, boys. InfiniKey-CPS1 will handle C-board (C.P.S.-B-21 chip) encryption key writing.

      CPS1 games that only have encrypted C-board:

      *Capcom World 2
      Captain Commando [TESTED]
      King of Dragons
      Knights of the Round [TESTED]
      Quiz & Dragons
      Three Wonders
      *Varth [TESTED]

      *Light gray plastic cases do not have enough room for InfiniKey CPS1

      Q-Sound games from that era (aka CPS Dash, CPS 1.5) that have both C and B-board encryption (yes, double suicide action):

      Cadillacs and Dinosaurs
      Muscle Bomber / Saturday Night Slam Masters
      Muscle Bomber Duo
      Punisher
      Tenchi wo Kurau II / Warriors of Fate [TESTED]

      Progress:

      I'm adding a "TESTED" note to the games above as I prove them. I'm fairly confident in the design at this point, so I will likely make official release in July/August, 2019.

      So, quick question, a dead CPS1.5, left unchecked for years, do I run the risk of acid damage on the board, or is it just a dead battery (or two in this case)?
      I've never seen acid damage on the C-board, but B-board is same as CPS2, so definitely a risk.

    • Yes!

      I have desuicided a few CPS1.5 and been lucky so far to not have had battery damage on them but one was starting to look a bit wet on the edges.

      It's always a risk, you can always replace with batteries for now to keep it playing and then remove and InfiniKey. Or if it's just sitting there doing nothing remove batteries and wait

      I just did 2 CPS1.5 boards last weekend and have 4 suicided CPS1 sets on the way from another friend to be desuicided too. Will get them going but let them know this is in the pipeline for later.

      Does this require any modification to the game PCB other than soldering on the CPS1 infinikey (as in no trace cutting/etc.)? I didn't think it was possible to write a key to the C board while it was attached and unmodified.
      No mods to original hardware. It will make more sense to you when I get photos of the protos.

      I have a punisher that I have phoenixed, and a Slam Masters that refuses to phoenix (but works with punisher roms). Really want to get this SNSM working correctly so eagerly awaiting word.
      Dude, that sounds like just a pile of junk. Why don't you mail those to me and in return I'll set you up with a few amazing games such as Martial Masters and Bad Dudes.
    • Just waiting on some parts (I realized I needed lower profile connectors in order for the CPS1.5 board stack to still fit in the case) and then I'll be testing on a friend's Punisher and someone is sending me a Tenchi wo Kurau II.

    • @Derick2k and @xtrasmiley were kind enough to send me more boards to test!

      Derick2k's Varth really helped me refine my program because I learned that some CPS1 games interrogate the C-board processor very early on. My Knights of the Round and Captain Commando to not do this. Also, sadly I discovered that the light gray cased games, Varth and Capcom World 2, do not have the head-room necessary to fit the CPS1 InfiniKey inside the case :( :(

      xtrasmiley's Tenchi wo Kurau II board looks to have been used as a battering ram (courtesy of surface shipping, I assume), but came up with the InfiniKeys the first time! I still need to do another board spin to address a mechanical issue, but I think it will be golden after that.

      The first post has been updated with progress and projected release time.

    • That's great, I was just wondering what was the project status yesterday.

      It should be possible to use this also to reprogram the keys of a C-board with a fresh battery, like the CPS2 one, right ?
      So it will still be useful for Varth & the Capcom quiz game.
      We can do it with an arduino of course but I guess an ad-hoc design will make it much more convenient.

      Yup! Good point!

      It is, but this will I assume need to be soldered and desoldered rather than the connections you make with an Arduino so it's really more of a permanent solution
      Nope! No soldering on this one :)

      Not sure what UD means by not enough headroom in the case though, really keen to see how this thing works
      It's pluggable so it adds height to the board stack. Anything with a case only has so much room inside.
