This early adopter program is very, very rushed. Reading through the details in Japanese, it is very clear that Nintendo pushed this press release out at the last minute and none of this is actually ready yet. Mockingbird has translated the lists and details, so I won't do that again. Instead I'll expand on the nature of the program:

- Nintendo is confirming that they will sell NES VC games on the eShop for 3DS. But they will not be released on Sept 1st.

- Instead, on Sept 1st they will be pushing out "early bird editions" of the free NES games for those who bought and registered their systems before the price drop. Only these systems will be able to download and play these NES games at that time.

- These versions sound like beta emulated versions. There will be no digital manuals included, and while you can switch the controls from player 1 to player 2 for certain games which allow for such play, there will be no cross system multiplayer supported at all.

- Eventually at a later date, complete versions will be released for actual sale on the eShop. When this happens, those with the "early bird editions" will be able to update to the full versions for free.

- For the GBA VC games, it gets even weirder. While there is no release date for those other than within 2011, Nintendo is outright saying that they currently have NO plans to ever sell such games on the eShop. This is something specially for early adopters as a reward, and are considered "not for sale" releases.
