Puyo Puyo 2 is, in its original form, a Japanese puzzle by Compile that was hugely popular in the nineties, centered on matching colored bubbles to build chains and send penalties to the opponent. The version this entry documents appears catalogued with the ZZZ-UNK prefix, with no solid information on whether it's an unofficial translation, an amateur adaptation, or a dump from another system mistakenly associated with the Atari catalog. Rather than asserting an unsupported target platform, it's fitting to flag that uncertainty: it is, given the current state of available documentation, one more piece of the preservation archive pending further research.
