Here is an archive of information on Sega-specific magazines published through the years. Where possible, I've provided scans of the full issues. These scans are in PDF format and some of them are very large (ranging from 20MBs to 100+MBs). I advise you to right-click them and save them to your hard drive so your PDF viewer or browser doesn't crash due to the size.
