For some context, I am replacing the motherboard for my 2DS by ordering just the motherboard online. I do not have a spare 3Ds to do the system transfer with. From what I am seeing with the steps to perform a PC-based CTRTransfer, such as the sources here and here, I will need to have both motherboards on at once to complete this process. Is there any way to circumvent this, or am I going to have to waste money on a spare 3DS to even think about doing a manual system transfer?
