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.
