R4i GOLD 3DS now supports Nintendo 3DS Ver 2.0.0-2(J,E,U).....no additional updating is needed....r4i gold to my knowledge is the first flash card to support the new firmware...and Acekard team release the updating patch for both 3ds and nintendo dsi v1.4.2 at the same time..check out the AK2i update for 3DS2.0 and DSI1.4.2 here. So far DSTWO,EZ Flash Vi,M3i Zero are confirmed not working......stay tuned... Update: Acekard 2i has already bypassed the Nintendo 3ds 2.1.0-4 and dsi v1.4.3 firmware update
yet,according to today's news,dstwo can support v2.0 as well.i think,more and more cards will realize this goal,just the matter of time.
