Hacking Why should I switch to sysnand?

[uyjulian]

I think emunand+a9lh is better if you have a faster+bigger SD card. Saving/loading streetpass/spotpass data will be faster (it takes 10 seconds on sysnand but 3 seconds on emunand for mario kart 7) and it will prolong the life of the NAND in the 3DS. It's very easy to replace the SD card, but good luck replacing the internal NAND.

Also, it's possible to switch NAND easily so if you want multiple regions, you can turn off your 3DS, switch SD with another one, then turn on your 3DS. Also, if you don't want other people to mess with your NAND, you can take out the SD card and the 3DS will not boot. (with a9lh anyway)
If something goes wrong and your 3DS does not work anymore, it's possible to decrypt your savedata without the 3DS.

The only real disadvantage is that you need an SD card inserted for things to work, but I wonder what is the purpose of using 3DS without an SD card? You need an SD card in order to change Home Menu layout/Home Menu theme/StreetPass/SpotPass/SD extradata/install games anyway...

-less space taken up on SD card
-longer life for your SD card (reads and writes to NAND are done on the actual 3DS NAND chip not on your SD card. SD cards are only good for a certain number of reads/writes so extends life)
-only install DSi/GBA once
-closer to a truly hacked system ... feels like you've really beaten your console

The longer life thing isn't really a plus as the nand on the 3ds has the same issue, only so many read and writes. I'm sure people would rather have am sd card die instead of the system.

I'm thinking of switching to sysNAND too, if I never installed anything to TWL NAND, nor used the AGB firm before, should I just switch the CTR NANDs and ignore the TWL and AGB partitions?

Once the NANDs have been switched, can I remove the emuNAND partition by copying the SD contents to a PC, formatting the SD, then copying everything back, or are there more steps needed?

you should still switch all of them, because you likely wouldn't be able to use anything under TWL_FIRM (like DS games). better safe than sorry.

yes, you can just copy everything, format, copy everything again.

How do I get to the aureinand config? Holding select doesn't work.

--------------------- MERGED ---------------------------

Nvm it works now.
Flashing emunand.bin to sysnand...

Don't flash the emunand.bin
You want to extract and inject the emunand partitions minus firm 0 and 1

There's an option in decrypt9 to flash a .bin but keep a9lh
All works fine. <3

Lately lots of people are moving their a9lh emunabd to sysnand. What benefit does this even give, theyre basically the same.

another way to look at the issue is to turn the question around and think "if i have a9lh, why would i still want emunand?" this will probably lead you to the conclusion that emunand is redundant. unless you have some very unusual personal requirements which are different from those of the average user... you just don't need emunand, so you may as well use updated sysnand.

...ugh, have you ever known anybody who had a Nintendo System die on them because of to many read/writes to a nand? think about it.

People are still selling the original Nintendo.

Now how many people have complained online about not being able to write data to their SD card?

Yeah, the console is 5 years old now, and I haven't heard anybody say their NAND died from normal use. SD cards are a lot more delicate. I don't know anything about the actual hardware technologies though.

 

[NekoMichi]

Unless the user is constantly installing new games, the amount of write operations to the 3DS NAND/SD card should be minimal compared to the read operations in day-to-day usage, right? (As compared to the writes on an SSD in a PC during everyday usage, for example)

I've never had an SD-card die. I've heard 1M writecycles per sector, not sure it's accurate though. $1 dollar SD-cards from eBay or user error is probably at fault most of the time.

some of the main ones are saving space on your SD card, and no double-installing GBA and DSiware. the main "CFWs" prevent writes to FIRM0/FIRM1, so an update can't overwrite arm9loaderhax, nor can something like sysUpdater. it may also be faster, depending on your SD card.

i myself also swapped nands and then wiped my emuNAND.

and yes the sysNAND now works just like my emuNAND was,
i wanted a cleaner mSD so i did the swap and wipe

worth it imo.

damn, i was too lazy , so i only dump/injected the CTR nands XD..

is there any other side effect other than dsi/gba nds games wrecking ?

i only use my n3ds for 3ds(i mean the cias obviously xD) games i use my og3ds for gba/ds etc.

so am i fine with having dump/injected only CTRnands on my n3ds?

edit: the reason i was lazy to dump the rest with the exception of firm0/1, was that i thought that the dumping would take long, like with CTRnands ?

the twlagb etc. i thought each of them also would take alot of time to dump , @ _ @ maybe it wouldnt have but oh well, i already have emuNAND wiped so i cant re-do the process. and also i am not using my n3ds for gba/ds games >< so i hope i am fine with the way i flashed.(only ctrnands).

For me, it was removing the emuNAND and regaining all that new space on my SD card.
There's other pluses, like only needing to install DSi/GBA games once and a slightly faster boot time. But for me, it's the free space.

Do you have any emunand.bin backups?

There's a thread every other day about a user having problems with their SD card, and the answer is usually that it's become corrupted!

It's not that it exceeded the numbers of writes though, is it?

I have dealt with many systems that have died because or the nands shitting the bed(that happens when you repair and hard mod systems a lot) the brand of the system doesn't matter(I have dealt with it on all of the big 3). Also old systems seem to last a lot longer than new systems(hint the 3ds isn't an old system), they don't make them like they use to.
I have flash drives and sd cards that are older than the 3ds that have been used like crazy and still work. Flash memory is a fickle little bitch that can just die(hint nands are flash memory)

It's not that it exceeded the numbers of writes though, is it?

No it's not, flash memory can just die. Some brands are better than others(some brands have a high failure rate). Older flash memory seems to be way more stable than new.

I've had a number die on me. Two were Sandisk, two were Transcend, 1 was Kingston, they don't die completely when they do decide to go, they just fail to write any further data.

I have yet to have my nand go to read only.

You just named off all the brands I refuse to buy lol. Although old SanDisk are reliable, I have a bunch of 2gb cards that are really old. Kingston is just trash, every flash drive and sd card I have had from them has died. I stay away from trancend because I know too many people who have had issues
