Is there a file validity check built into azahar?

[red storm]

i suppose you could store a hash for each dump - this is what i do. alternatively if the game loads, it is probably valid 😅

[shy tangle]

How would I know if the hash is valid though? I’ve done it through .3DS files using no intro but trying to do it for .CIA which I can’t seem to find the hash for

[red storm]

what is no intro?

i think the process depends on what platform you have

on linux i can do sha256sum -b file.cia > file.cia.sha256 to create a hash, and sha256sum --check file.cia.sha256 to verify the hash

it looks like windows has similar functionality in powershell with Get-FileHash

[shy tangle]

It’s a list of all the hashes for games so you can cross check to make sure yours matches the verified ones they have to know if it’s an exact 1:1

I can check the hash but I don’t really have a way of knowing if it’s the original hash if that makes sense

[red storm]

huh, i kind of assumed that dumps would have a different hash depending on the console

if you bought your game legit and dumped it properly, that should be the "original hash"

after your initial dump, you can create a hash and rest assured that your file is valid

[shy tangle]

Yeah, what if something happens during the dumping process though and it isn’t apparent?

[red storm]

then your game wouldn't work

if your game is working what is the issue?

the dumped files have signatures that can be verified using a tool like ctrtool too

[shy tangle]

Ahhh, I’ve heard other things like if there was a corrupted file the game could still technically work but may crash when it gets to that file

Can ctrtool check cia files?

[red storm]

yeah i am pretty sure it can

ctrtool --verify <file> will verify any hashes and signatures in the file

for all intents and purposes you should be good atp

or i guess you could dump the game multiple times and see if the hash changes. but that takes too long imo

[shy tangle]

Yeah I agree lol

Thanks!

[shy tangle]

I checked and apparently you can’t verify cia files with crttool sadly

[red storm]

what did you have issues with?

i was able to use ctrtool with CIA files just fine 🤔

[shy tangle]

No issues, just wanted to double check. Maybe we could check hash files if we have the same games?

[red storm]

i'm pretty sure the hashes would be console specific

[shy tangle]

Oooo I gotcha

[red storm]

just an assumption though

[shy tangle]

So you download ctrtool and what do you do to verify cia?

[red storm]

i just run the command. if your game is legit, ctrtool says everything is "OK", and your file hash has not changed, your dump is very likely to not be corrupted or anything

you might need to dump seeddb.bin for it to work properly

[shy tangle]

Gotcha, and I can just do that with godmode9?

[red storm]

i can't remember exactly what gm9 can verify

it is probably similar

a simple file hash is good enough for me lol

[shy tangle]

As far as getting the seeddb.bin though can I get it from gm9?

[shy tangle]

Ahhh, thank-you’

[red storm]

fwiw azahar doesn't need either file anymore

[teal heath]

interestingly enough, this isn't true for switch emulation. it's funny watching people run corrupted dumps of smash where characters start t-posing in the middle of the match, lol.

[red storm]

oh interesting

[shy tangle]

But it isn’t true for 3DS and WiiU games?
