Bubble Trouble appears catalogued with the ZZZ-UNK prefix, typical of archives that group pieces of not fully verified status or authorship: its name suggests a bubble-shooting or chain-popping mechanic, a genre very popular in the casual catalog of the nineties, but there's no solid information confirming the exact target system, authorship, or release date. Rather than risking unsupported data, it's fitting to document it for what it is: one more piece of the preservation archive awaiting the community to complete its story.
