Hacking ANNOUNCING: GATEWAY 2.1 "OMEGA" PUBLIC RELEASE

[Ris312]

hm..i downloaded all 3 programs but im lost...what now? how to i actually compare these values? :/

then just copy / paste the resulting CRC from step 5 into 3ds.essh.co and see if you get a match.
(edit: The rom needs to be untrimmed for the CRC to match)

I use a program called 'Hashtab', it adds a 'File Hashes' tab in the file properties box.

oh wow this hashtab is fenomenal, neet and fast..and small

Thanks a lot!

By the way,whta exactly IS CRC32 and MD5 (do i need to check MD5 anso or is CRC32 ok, so i can safely put 3DS roms on Gateway?)

MD5 is more accurate

MD5 is more accurate

Do you check your roms, and what do you use to check them?

 

[uyjulian]

Do you check your roms, and what do you use to check them?

the "md5 file" command

MD5 is more accurate

Great answer.. not.

CRC32 was used in the past to error check files. Basically, it's like a hash in that it's a fixed length string generated from a dynamic length output. If you download a file and generate the CRC32 from it, and it's not the same as listed on the website you downloaded it from (provided it tells you what it's supposed to be), then the file is corrupted, or worse, has been maliciously altered. CRC32 is very easy to manipulate though; adding 4 more bytes to any file is enough to create every CRC32 sum you desire.

MD5, on the other hand, is more of a hashing algorithm; there are "collisions" - two and more inputs generating the same output - but it's a lot harder to get to a valid one. So, generally speaking, MD5 is the better choice for file integrity checks.

wow, i love your answer thanks!

but by the way..where can i find MD5 code that i can match with one i got from 3DS rom?
On 3ds.essh.co there's only CRC code, not the MD5 code.... :/

You have a Gateway ?

you do realise that post is nearly 2 months old.....although i suppose it is kinda funny hunterb joined the dark side after loving the R4 so hard

 

[osirisjem]

kinda funny hunterb

It's much more than KINDA funny.

I never knew ROFL.gifs were not allowed. Sorry.


Huntereb - How's your Brickway ?

I think this thread has run its course.

The newest firmware for Gateway 3DS is Omega 2.2, the discussion thread can be found here.
