update 2012-10-23
We have 2 PCBs of the same game.
The first one was previously called: Juno First (bootleg 1)
The second one was previously called: Juno First (bootleg 2)
It is now confirmed that they are the same game, identical to the Konami original, but from an unknown manufacturer.
We are lucky that out of the 2 we could get a dump of all 3 PALs (green, red, blu).
