So they are professionally cloning gateway...? Wonder how this one is gonna go over considering gateway's attitude towards clones before...
What's suspicious is how they are talking so openly about it. The other clones were really discrete about being Gateway copies, while here they are practically screaming "OUR CARD IS A GATEWAY CLONE!!!". As said in the other thread, this is probably because they have a deal with Gateway.
I personally think that the deal (if there is one) is something like "You, Gateway, authorise us to clone your card, and in return we share our exploit / technology / ? with you.". In the page, they say the DSTwo+ is going to be compatible with "any firmware 3DS". It can be a translation error, or it can be the reason of this.
Or maybe they are just like "lolz Gateway we are cloning you what are you going to do". And actually, it can possibly be a good strategy too, because if Gateway respond with some more 3DS bricking, their reputation will decrease even more (less sales for GW and more for SC), and if, on top of that, the DSTwo+ price is lower than the price of the original Gateway, then they can take over the 3DS Flashcards market completely.
But anyway, we will only know the truth when the card comes out.
