Daedalus

Thanks for helping, but the 670-xxxxxx numbers aren't codes for games - they're the product codes for the covers for games... if that makes sense.

Every part of a release has an unique number, be it the box, manual, cartridge shell and even the internal PCB - the four digit numbers you were replacing describes the package as a whole -Black Squirrel (talk) 06:23, 19 February 2015 (CST)

Hi, Black Squirrel. Hm. I wanted to contribute, since i have over 1100 MD games in my collection. I personally differentiate different region variant via these 670-*** numbers among my collection. For example Batman Returns, i have EU, UK + AU and the Cover IDs are the ones I consider to be the indicators. Which numbers are relevant to you guys then? So I can contribute...
