There can be a few differencies in the two games code, but impossible to know for sure that it's not the rom dumper software's own code.
The only way is an attack from Pc,or Mac, real time.

.Just have to hook up the 3ds with the computer,somehow, and then the fun begins.Right now, I don't have a clue what to do after you hook up the 3ds to a Pc.

My knowledge is too old now needs to be refreshed 200%. We need and electro-technician, a mechanic, and two programmer dude.One who knows Linux, and one Who don't.Our electro technician, and mechanic have to make a special cable what connects to the 3ds through the game card slot or the sd card slot, the other end of the cable goes to a Pc usb slot.And then the two programmer dude in 24H-24H workshift's can work on reaching the firmware in the console,and set it free.If they suceed, the end result can be something like the PSP's softmodding was. But we need serious and willing men to do this.
And at least one team per state, and at least ten team per country in cooperation, so they don't doing the same mistakes.One team can do it of course alone, but it needs to be started quickly before Nintendo kidnaps everyone.
