Dreamcast Collection Spreadsheet
This is a simple spreadsheet to keep track of your collection of Dreamcast games. It contain a list of every North American release, independent release, and a few European releases that never made it to North America. You can set whether you own each game or not, leave a note regarding its quality, and it will automatically count them to let you know how many games you have in your collection and how many you are missing. There is even a second spreadsheet to keep track of official hardware that you own, in case you are trying to collect all the hardware as well.
