Sega 32X, part of GameDB.
32X.data.json: All data, structured in the JSON format32X.data.tsv: All data, structured in the TSV format32X.release_dates.pdf: Histogram of release dates, stratified by region32X.titles.json: Mapping of serial numbers to game titles, structured in the JSON format
For now, I am just using the CRC32 hash of each game to uniquely identify it. In the future, more sophisticated approaches can be discovered.
