Here's something that I was thinking about last night.
The old Konami million seller list doesn't include any SH titles, which would suggest that none break the 1m mark, until 2004 at least, however that list also doesn't include games that are very well known to have sold over 1 million units, such as Goemon, Twinbee and Gradius, all which were millon sellers on the Famicom (Japan only) so it seems like the list is incomplete for some reason, did they only add games they wanted? is there some soft of licensing issue?
I was, however able to find an old IGN article claiming that Silent Hill 2 had sold over 1m units in around a month after its original release, havent found data on the original, but given the early big sales of the sequel its likely the original got to 1m as well.
