Recently the Gateway 3DS card has been a hot topic.
Quote from GBAtemp:
"Gateway & existing 3DS roms
I have just received confirmation from someone who currently has the Gateway 3DS in their hands that the card does indeed support the existing 3DS ROM dumps. Which means the existing 243 releases are confirmed to be legit/valid, and potentially playable (depending on the region). There shouldn't be any need to redump games. The source of this information is reliable but I do not wish to disclose their identity as they prefer to keep it secret."
I am looking forward to its release!
