If anyone is still wondering about the date change, this is something that has been done pretty much every time, starting back way before Nigoli and I were managing the events here. Even when there was a special screening or when US cards were leaked early by retail employees, the WC hosted on the site here was always changed to the official starting date of the event, for the sake of consistency.
For those wanting a specific date, it is totally possible to change the date of your pkm using Pokegen.
For those wanting a WC of a specific date, that is almost pointless when the WCs are identical. The point of the Event Gallery and the Event Database before it was to give people the opportunity to obtain an event Pokemon for their personal use that they would not have normally been able to get. It is NOT for the purpose of trying to trick people into thinking that you have an ACTUAL event Pokemon from a special one-day screening of a movie before the official release. It is especially not for the purpose of trading it to people under the false pretense that it was obtained in person.
But saying this isn't going to stop people from doing what they do, but we still won't accommodate such a trivial thing as the date.
ESPECIALLY since the date is the most irrelevant point on a pkm. Since it is controlled by the date of the DS system it was received on, the date for any Pokemon can literally be ANYTHING within the clock range of the DS hardware.
This isn't a rant, I'm not trying to put anyone down, and I'm not angry or upset about anything.
This is something that really hasn't been fully spelled out in a while, so I thought it might be time to lay it all out again.
So there ya go.
ANYWAYS,
Event Collection zip update coming tonight, finally.
Edit: I guess I should say that the recent inclusion of the US Larvitar and the UK Victini were both exceptions to this. There was a lot of discussion about whether to include these cards, and we decided to provide secondary download links on the Gallery entries simply because the distributions were SO far apart and marketed for different regions.
