> - Backgammon (What's missing in its driver ? adp.cpp)
My recent investigations found that this actually runs on basically the same platform as Mann, oh-Mann. It seems unrelated to the standard adp/Merkur hardware (though the slot machines in stellafr.cpp apparently run on a variation of that).
Both are electronic versions of classic board games with no screens, just a lot of colored lamps and LEDs. They also roll physical dice for each move, which will have to be loosely simulated somehow. Mann, oh-Mann also reads out the result of each toss out loud in German, and that seems to be coming from some controller board that isn't documented at all, let alone dumped.
As Haze says, Zero Team 2000 is a working clone of this, and its code is comparable enough that reverse engineering has already helped improve emulation of the original. The problem, like Seibu Cup Soccer, is that it uses COP features that were never really used in any other game. Some of the COP commands aren't used in any of the games, except in some dummied-out routines. Seibu had a habit of creating sophisticated hardware platforms and then underusing their features; for instance, the SPI motherboard has connectors for 3P and 4P inputs, and a few games even seem to be reading them as in Seibu Cup Soccer and Zero Team, though there was never any SPI game that supported more than two players.
