Hacking Nintys new copyright protection (BCA)

[BenieUK]

For us Mod-Chip users could we not just store BCA data on the SDCARD ? and Mod-Chip could just read it from there?

Anyone hears something like an ABGXWii coming? I wouldn't mind to patch my ISOs. Though Hermes said:

An automatic patch can be released soon, but for now, that's the procedure.

Honestly, I'll wait and see how all this turns out...I'm shure it will end up like all the other "protections", question is how long it will take this time.

And thanks for this Thread, realy useful.

epic protection:

0000000000000000 0000000000000000 0000000000000000 0000000000000000
0000000000000000 0000000000000000 0000000100000000 0000000000000000

juste one byte, like in CD in the 80'

\o/ Nintendo...

Seriously....

lol
Next protection: two bytes xD

Oh look at me, I'm posting in a Wii hacking forum so that makes me a hacker. But wait - I don't know the difference between a bit and a byte. Ecks capital dee.

Never said I'm hacker... and sorry for the typo

How do USB-loaders currently fix this?
NSMB now works on most usb-loaders. Is that a game-specific hotfix or will it work for all future protected games?

 

[XFlak]

i'm 90% sure that the fix is game specific i'm sure they'll incorporate a global fix eventually (when its needed/ when they get around to it/figure it out)

 

[Screemer]

there is a gecko-code to circumvent the bca-check: http://www.eurasia.nu/modules.php?name=New...le&sid=2491

i think this process could be easily automated.

 

[VashTS]

that sounds like a good plan to me, patch the check right out...why even bother having to insert crap, its easier to take it out

When will N learn that now that piracy has started, stopping it is almost impossible? Adding the anti-piracy after the fact isn't going to help. D3-2 was a step forward, but it's only time before the modchips show up.
If they want to stop most chips, they'd need to make D3-2 units with the whole circuit board potted in epoxy.

The BCA protection took what, a day or two to crack on NSMBW? If we're cracking AP protection in days, and it takes weeks or months for new protection to show up, N is fighting a losing war.

except it took this long for how the protection actually works to make it to the public. The earlier cracks worked, but they merely patched the error to return to the game instead of hanging. This finally fixes the error at the root of the issue.

Still, you're right that they're fighing a losing battle.

 

[Livin in a box]

Me and my WiiKey v1 are still fighting on here with GeckoOS and that cheat file. ^^

I don't really understand any of it but is it not possible to just remove all traces of BCA off an ISO image?

 

[longtom1]

flatmod/flatmii done a bca editor downloaded it but haven't looked at it much I think you open the ISO and edit or remove the bca code

 

[maduin]

just add the BCA info to WiiTDB, similarly to how Title information is stored and used in loaders, so it will automatically downloaded when you download a title.

 

[Hatsu]

We hackers will win against Ninty and their lame Anti-Piracy (only good one is NSMB, the whole of GBAtemp was up in flames!)

 

[FenrirWolf]

Yeah, we're all such 1337 hackers for running programs that other people have compiled for us. >_>

CODE it froze
but didn't read the BCA
im saying bad dump
someone prolly using rev14
ill know once i play this ntsc
almost done adding
I'll check the ISO
then i gotta get my bow all over again
* archive sighs
ok its done, im going to play
James.Camerons.Avatar.The.Game.USA.BCAFiX.Wii-ALMoST
did u guys try that 1
yet
the PAL release is corrupted
one block at 76776
I'd imagine that one uses that BCA someone posted earlier?
then more broken ones at 119094
avatar DOES NOT CHECK THE BCA
if it doesnt chk the bca then why did James.Camerons.Avatar.The.Game.USA.BCAFiX.Wii-ALMoST get rls ?
because they are idiots?
lol
they claimed that nba2010 has the BCA check too
and what was the issue?
60MB of corrupted data

I concur, the NTSC version worked without a BCA patch.

 

[Slimmmmmm]

We just need a standard to know where to store the BCA-Code in the ISO, so that every Mod-Chip and every Softmod know where to search.

OUTSIDE OF THE DISC! Or else nintendo can check if the data at that offset matches the BCA data, which it does not on retail discs.

I agree 110% but some people don't even get it at all.

Some people suggest we add the BCA data in the header, or end of an IOS image...NO ! ! !
In fact there is a scene release group (ALMoST) that are suggesting we patch the discs

The BCA data NEEDS to be in a small EXTERNAL file and loaders will need to support this, to get the best from "the scene" we NEED to keep things as 1:1 copies whenever possible.

 

[Jaz808]

There might need to be a few methods for different loading methods
SoftChip / cIOSCORP - in code or patch iso
Backup Loaders - in code or patch on the fly
USB Loaders - downloadable like covers, cheats, game.txt

 

[TroyTheZombie]

heh?

so, avatar NTSC version doesn't have BCA protection?

 

[Pakatus]

heh?

so, avatar NTSC version doesn't have BCA protection?

From what i got here...it's not a BCA Protection afterall...just a bad PAL Dump.
Anyone can point me to the NTSC release name?

 

[MikeyTaylorGaming]

is this trying to say that when a game is dumped it doesnt rip with BCA data or something?

so you have to use an original game to find the BCA and then patch it to a ISO file?


and new super mario bros BCA is

0000000000000000 0000000000000000 0000000000000000 0000000000000000
0000000000000000 0000000000000000 0000000100000000 0000000000000000

and that's what you patch the main.dol with?

thats my interpretation anyways, since he was talking about PPF patching just above that


i dont fully understand this still but its a good thought i guess

haha
