Nintendo's said to be prepping a Virtual Console-like service for DSi enabling users to download and play Game Boy and GBA titles.
The news reportedly comes from a Club Nintendo DSi preview event held at the weekend, attended by staff from website Kombo.
Nintendo's apparently told the site that downloadable Game Boy and Game Boy Advance titles are coming to DSi, but that the service has only been confirmed for Japan so far and offerings will initially be limited to first-party games.
On top of that the platform holder said that you won't be able to save and run the games from an SD Card.
However, a Nintendo UK rep played down the report, telling us: "This is pure rumour and speculation and nothing has been confirmed by Nintendo of America."
Expect plenty of DSi info from GDC tomorrow afternoon when Nintendo's president Satoru Iwata will be giving a keynote speech.
