Hacking [Tutorial] How to have two emunand (MT + CFW) on the same SD for 4.X 3DS

[gamesquest1]

and for installed things? like eshop games or program like savedata? i can launch my eshop games on NTR CFW if is linked with 9.5 emunand?

no, items installed install a ticket to the nand you are currently running, so if you install anything in any of the nand's sysnand/emunand1/emunand2, it will only work in that particular nand

also the NTR CFW does not run unsigned cia files

so just to make sure everyone is clear, this will not allow people to run cia files in anything other than the normal leaked cfw, unless you own a MT/gateway card

Hmm so the utility of dual emunand what is? o.O
Someone can try export/import save with savedatafiler and then launch game on NTR CFW and see if importing works? At leat before im doing all this work for nothing if not work XD

its so you can run 9.5 classic mode (for your retail game carts/eshop access)
and 4.x cfw with your cia installed content, all from the 1 SD card

But... many minutes ago you said that all emunand partition have their own contents that not share... and now "4.x cfw with your cia installed content, all from the 1 SD card". Can you explain better, please? with dual emunand, cfw 4.x can have installed content or not?^^

you cannot run cia files you install on the cfw in MT classic mode, that's all you need to know

they *may* show up depending on if you keep the nands linked, but they are not "linked" in the sense that they will run between nands, they will just "show up"

its simple, but hard to explain in simple terms, it all just depends on if you unlink each nand, but ultimatly it boils down to what is installed on one nand may or may not show up in either of your other nands....but will only run in the nand it was install with

 

[Lord M]

In other words: also importing or exporting save with savedatafiler dont work with dual emunand?

I'm surprised people want to go this far when there are simpler options, and the end result stays the same (playing rom/region-free/homebrews).

I need to know... since now i have 2 SD, one with 9.4 emunand and one with ntr cfw... i can extract both emunand and then collocate both in new one SD, or i need to do all this on a existing SD with just an emunand inside?

You can do what you want. If you prefer to mantain the two old Sd as backup (wise choice, you can format them later), you can use a new SD.

Remember only that if you want to inject the NTR emunand (that is the same of a GATEWAY emunand) with emunandtool, it's bettere to first format the emunand with the gateway software, otherwise without the "GATEWAYNAND" mark in the first bytes of the first sector, emunandtool wont work.

Obviously you can mark the first sector with an hexeditor and use emunandtool, or inject both the emunand by hand with dd or BBcopy.

When entering CFW my bottom screen doesn't blink white, it stays white, and does nothing. Help, Anyone?

The cause is a wrong emunand or emunand in wrong place.

Did you followed all the steps exactly, or you changed/omitted something?

Can you boot the first emunand? Did you used the boot.bin in the attached zip?

If you open the SD disk with an hex editor like HxD, can you see the second emunand starting at sector 0x00200001?

 

[AtlanticBit]

yeah, I did everything correctly and can boot 1st emunand

 

[nop90]

Maybe you tryed to extract the cfw nand from the wrong disk.

Open your CFW emunand dump with an hext editor, if it's correct you should see the string "NCSD" at position 0x100.

 

[AtlanticBit]

there is a NCSD at po 0x100

 

[AtlanticBit]

whatever, restored my 2SD card backups

In this case, you can tell me how to do? Where collocate the 2 extracted emunand by different SD's into new one?

 

[nop90]

Make a copy of the SD with the NTR emunand on the new SD with windiskimager, than follow the tutorial.

It should be possible to use this to have emuNANDs for GW and NTR CFW in the same SD and switch between them, right?

Pardon my ignorance, but where can I find multiroploader.nds?
