Managed to get my hands on one. I've not really tested it out much but it's kind of like a Tamagotchi but with Digimon. It's supposed to be able to connect with (probably only older) official Digimon devices but I can't really test that out. I also am unsure of how it compares to official devices, as I'm fairly sure a real one doesn't have a feature to skip forward in time. In any case, the dump seems to work fine, but I cannot guarantee it won't do something wacky later.
I always name my stuff after the title screen (since unlicensed games often can have different labels from different publishers, etc.) but if you want a tad bit more information check out the wiki page on
Digimon 6 and the source.
