I was wondering if the data base on this site has different entries for things such as original print vs reprint; Green Label vs Black Label on PS One for instance?
I know that it does specify, for NES games, a number of screws in the back (which can differ between prints), and I believe it also has differences in labels for Atari games.
Since this is a... I guess you'd call it a "living database," the information won't always be 100% there. Though I might ask about it first, I imagine the site people wouldn't have a problem with you creating a separate entry (if it doesn't exist) for greatest hits editions and stuff (as I previously mentioned, something similar already exists with other titles).
