Hi Tempers, As the title says I have 2 3DSes and only 1 Gateway (I have Cubic ninja and OOT too). I want to run one on CFW with cold boot and one on Gateway. I have an O3DS 4.2u and a N3DS 9.0u. I want to know a few things: Should I update the O3DS to 9.2 to use homemenuhax and a CFW with cold boot then run the N3DS with the Gateway? Any drawbacks to updating? Should I use the N3ds with cold boot CFW for EMU nand and go gateway on the O3DS? Which CFW has the best compatibility? Rx-tool,cakes,rei or other? What do you think is the best solution to getting both systems on EMU nand without changing carts? Thank you to all who reply!
