Kiki kaikai and its non-jamma pinout. Why??

[Georgian2]

Hello guys,

here I have this bootleg PCB. It had an adapter soldered on and it worked perfect. Just by looking at the PCB I said this is jamma and I removed the adapter. Next plug in, dead short. Removed the PCB, checked resistence between GND and +5V and is high enouch, plug again - dead short. I tried another power suply and it went streight in costant curent mode pulling 3A at 0.2V. At this point I started to belive that it is not jamma.

Long story short, it is almost jamma pinout, expect the pins 27 and 28 on the solder side are +5V not GND! WTF? Why do this? Here is the pinout for it.
Be carful guys and always check before pluging in!

The bootleggers made a mistake and didn't bother to fix it, as that would cost time and money. I had a bootleg game cannot remember what it was now but the player 1 and 2 controls were swapped, that was an annoying one too.

This is a tough one if you only have controls for player 1 like me.

I didn't know Kiki Kaikai was an arcade game. I just got the PC Engine version.

The bootleggers did it to mess with you personally.

Come on, I can't be the only one who did it. 🤷‍♂️

I think it was Arcade 1st, I have the Super Famicom version it’s a lovely game.

But it was you they aimed at,everyone else was just collateral.

Damn, just plugged in a one of those bootlegs...
Can confirm you are not the only one, and I'm collateral damage

I had three of them and @Lurch666 bought the first faulty one I found and fixed it.

I then found two more and they both were shorted to gnd when I tested them. @Lurch666 kindly said he would look at them and found the same anomaly you have. He fixed by cutting a track to break the short.

Interestingly they worked fine for him and also on my Axunworks supergun. But @Nintendo Arcade borrowed one and on one of his JAMMA cabs it did the same short to gnd, and on his other it worked with noise on the monitor.

 

[Georgian2]

They work if you don't have the last 4 pins ond the jamma loom connected together or all 4 to GND.
most people don't have these 4 pins connected to anything.

I had forgotten all about this thread when @Alpha1 sold me that boot.
