I found a couple of 2600 carts today that do not appear to be listed in the DP guide. Upon closer examination, they're all Zellers games, as listed at http://www.atariage.com/company_page...mFilterID=2600 - but most of the ones listed there aren't in the DP guide at all. Is there some reason why that is, or is it just because they're unlicensed pirates?
FYI, the games are all loose, but I'd be quite willing to sell them if anyone's interested. (Time Warp is sort of spoken for already.)
