GCN way to automatically verify dumps for wii

[MarioMasta64]

is there any way i can automate the verification of gamecube and wii disc dumps in mass on a headless server by their id

example: my copy of pokemon xd gales of darkness is GXXE01

i do not want to use a gui and its preferred to be a linux tool (or even if theres an api i can use)

i found redump which is nice but i dont know any way to turn something like GXXE01 into http://redump.org/disc/1845/ do they have any kind of api?

basically all i need is any way to get the hash that the dump is supposed to be

ive also tried seeing if quick searching could help as a middle but it doesnt appear that you can search things this way http://redump.org/discs/quicksearch/gxxe01/

okay poking around i did find that they dont use the versioning:
so something like this works:
http://redump.org/discs/quicksearch/gxxe/
but is there a better way?

I don't know if it's good enough for you but I've made a bash script for that just now (needs wget and sha1sum commands):

im just doing this: redump_url=$(curl -Ls -o /dev/null -w %{url_effective} "http://redump.org/discs/quicksearch/$redump_code")

it would be nice if there was a way i could query this stuff directly

i did it this way after remembering that i had to also take off the versioning for images off of gametdb

i also save these hashes instead of just taking them everytime i go so that i dont have to bug the site owners with my requests (that much)

so i got it sorted out already but thank you anyways

unfortunately while it works 95% of the time you sometimes have moments where it goes:
rlee (ah yes the garfield game and this wii game right!?" no no lol
this also applies to things with multiple versions
i wish you could sort by console or search only for the games code but it seems like the filters on the site are lackluster

Wii backup manager implies directly hash codes to verify the integrity of a wbfs image. So maybe they are stored already. So basicly it needs to be read out and the image can be verified.

An MD5 Hash is calculated and stored in each disc transferred to a drive, so it's possible to verify the data integrity at a later date. The hash isn't calculated for ISO yet.

wii backup manager neither runs headless nor is it for linux it also doesnt check gamecube games so in all three ways it is useless to me

You could calculate the CRC32 or SHA-1 of the ISO first and then use that hash instead of the game code for /quicksearch/. Maybe that helps you?

maybe? the main issue is that crc/md5 calculations are really slow

i could use it and store the value for the first time then get it from the server and then use the gameid as a fallback but i want to be able to copy en masse before doing a check so that i can fix bugs if they arise without having to wait for verification for 5 years

i have like 300+ dumps and its unfeasable to do it this way when i do this in big amounts

 

[MarioMasta64]

it does appear that it is a method i can use but its on the back burner since id want something faster than calculating the hash before checking

 

[MarioMasta64]

the main reason is that i cant wait around for 1500 minutes because it updates a user accessible resource that should be made beforehand the calculations are done afterhand

im looking at the guides and there doesnt appear to be anything on hash checking dumps

Sometimes checking the commands would help.

this works for gamecube and wii?

I didnt have used or tryed them on my own. So sorry, u need to dig and try by yourself.
On the first look, with Wimms ISO Tool can be verified WII and GC ISO`S.
And with Wimms WBFS Tool can wbfs images be verified.

so i decided to take a hybrid approach to this by calculating the md5 only when it cant normally find the page and then searching it with that

and while it adds a little bit of overhead it isnt as bad since i only have to do it once and its somewhat rare that it happens

i can also try and assume anything not found is likely a bad dump
