PK3: Unreleased AGATE & SOFO Celebi (ENG/ITA) .

The international version of the Ageto Celebi Event was translated and programmed into Pokemon Colosseum, but was never released to players.

@HaxAras managed to use some codes and trickery to gain access to them.
 

Statement regarding the event:

Quote

From what I remember, the Japanese Bonus disk contents are available on international Colosseum saves and just dummied out.

 

So if you use fan-made action replay codes, you can access that content. And so long as you have earned enough Poké Coupons and purified all 48 shadow mons, you can get them as normal.

Thanks to @SkyLink98 for the Italian SOFO Celebi.
