Hacking Technical Questions on the gateway ultra..

[XDM]

Ok i have some rather odd questions or maybe dumb questions to ask about the gateway ultra

• how does the 3ds save encryption work? why can't we just pull "keys" or something from our backed up 9.2 FW 3ds then downgrade to 4.2 and inject it back into the nand so that launching games with lower FW does not corrupt retail cart save data?

• why does the profile exploit no longer work on anything past 4.5? i dont know but maybe the methoid of installing the exploit was blocked (installing exploit via ds flashcart) but now that we have access to the NAND files of the 3ds up to 9.2 cant we just manually re add those same exploit files to the same location as before but using another way such as dragging the files or the use of these .cia files to re install a easier way?

• can i make my retail cartridges save data not corrupt my savedata when launched on 4.5?
  does this have something to do with it?

1. Im not quite sure how it works, but the only thing I know is if you created a save on 9.2, you wont be able to use it on 4.x due to a different encryption.
2. Its been patched.
3. Im afraid not due to the different encryption.

ok slightly understand...slightly...
please bare with my noobiness got to start somewhere

but i still would like to know how save encryption works.
is it in a separate partition on the 3ds cartridge?
Are there even partitions on a 3ds cartridge?
How does the cartridge detect that your using emunand, the emunand is a direct copy of your systemnand so when launching a retail cart in emunand why does saves still report as corrupt?...
it has to be something to do with the keys... when you downgrade your using a generic 3ds image...so your keys are gone...maybe theres a way to pull them out your NAND.bin..

Have you read the sticky at the top of this sub? Read it and post any questions there, mmm is very good at following that thread.

yea theres some really useful stuff there

and yes! i got the 3ds X-loader app to work on my android even without mobile data!
now its 45% less annoying to boot to gateway mode and 100% safer with me not connecting to the internet at all now!

Some N3ds questions..

• when or if N3ds support comes to the gateway. would we need to have separate homebrew coding in account for the new hardware e.g the new faster processor and maybe ram and C-stick?
  and would we be able to take advantage of these new features on our gateway?

• Do you think we will be able to rip and play N3ds exclusive games like Xenoblade on our same gateway?

• Do you think with future updates would gateway be able to launch directly from the menu as a regular cartridge and launch exploit-less like sky3DS? Or is it physically impossible?

1. What is "Homebrew"? Is that like a beer making game?
2. I sure hope so.
3. I suspect it can happen. If not someone will eventually program one of those wifi SD cards to run a lite server to run the exploit so you won't even need a phone.

homebrew is usermade apps or games that are not made by or intended from the game company e.g emulators are a form of homebrew

also i think if theres a way to install a cia to your sysnand we can make a app that boots gateway mode easily
