I found that Gateway is getting a huge update that will work on up to 9.2 firmware... but the update is in a WIP state.
I need info about that MT-card before telling you if it can o can't rip stuff from 3DS... the thing you need is the Xorpad file from your 3DS that has the code to rip the rom and it's copied to your SD card when you do the exploit (Gateway Mode) to play 3DS games... Normally that's the way Gateway 3DS does.
if that card cannot create the Xorpad file into your SD card, then it means you can't rip the stuff from 3DS roms.
Edit: It seems that MT-Card is pretty much like Gateway in every way (Xcept for save editing that seems pretty much like a Gameshark for 3DS
) ... but I don't know if it really supports versions above 4.5 or may work with 9.2 as well.
But it seems like you can do the same stuff like on Gateway... Exploiting via Profile... in that case... then it must be a way to get the Xorpad you need to rip 3DS roms.
Edit 2: You've mistaken... MT-Card only works on 4.1-4.5 3DS firmwares... so forget it. unless you have a quite old 3DS with that firmware... you better have to buy Gateway and pray the update comes very soon, also... you must have your 3DS to 9.0-9.2 Firmware... anything upper that version, means bad luck for you.
