I had an Acekard 2i sitting inside my DS Lite. I just bought a used 3DS XL and I was excited to see that the firmware was Version 4.2.0-9U because the Acekard 2i will work with firmware up to Version 4.3. After flashing the card to support the 3DS XL, it runs games perfectly. The other cool thing is that the firmware is old enough so if and when the Gateway 3DS is released I can take advantage of that as well. I have quite a few customers on eBay looking for an Acekard 2i, so if you want I can put you into contact with them if you would like some money to put towards a SuperCard DSTWO because that looks like the only DS flashcard with 3DS support that will continue to be supported. Not only that, it can also emulate GBA games as well.
