> Within the reveal of the Pokémon Virtual Console 20th Anniversary Releases yesterday, another small bit of information slipped by. This information is the file size of each of the games on the Nintendo 3DS. Previously on the released images of the download cards, the file size was marked out, but now it has finally been revealed. Each game requires 11MB of space on your SD card in order for you to download upon their release on February 27th 2016 globally.
> Serebii confirmed

The actual rom size for each game is around 1MB, so 11MB is a pretty significant increase. Assuming its not entirely down to the trading ability improvements, what else do you think they've added in? All 721 pokemon in 8 bit format?
