Hacking [release] Use blocked DS flashcards on 3DS, probably N3DS too.

[gamesquest1]

Hi cearp, I would like to know why that is, technically.
Using my super old CycloDS Evo would be so totally awesome.
As far as I understand, these carts are just masquerading as real DS titles in order to boot, until Nintendo blacklists them.
So why isn't it possible to unblacklist them like you did for the GW blue card?
Thx for any detail.

im not quite cearp, but i can help....basically up until 4.2, nintendo just blacklisted cards that where known to be getting used to bypass the checks....but then in 4.2/4.3 (i think 4.3) they upped the ante and blocked based on the hardware, this was achieved via TWL_FIRM not the ordinary whitelist updates.......so this covered a whole range of cards that use that specific saving mechanism...so even cards that where blocked in say 2.0 could pretty much be technically double blocked....even now the whitelist is bypassed, the TWL firm check still applies, and blocks cards based on the save method

so why cant we do this with TWL_FIRM....well simple, atm there is no way (that i know of at least) to install cia files with a lower version than the currently installed version....(well actually the gateway downgrade achieves it by whatever means)....but yeah spoofing the version number doesnt actually work, it was more of a fluke that by chance a invalid whitelist pretty much just disables the whitelist rather than downgrading it

Thanks for your input.
It seems cearp did manage to bypass TWL_FIRM, otherwise how could the GW blue card be working on 9.x ?
The Cyclo Evo has never worked on 3DS, since launch..

blue card was only blocked due to whitelisting....not the TWL_FIRM block....basically the only cards being blocked by TWL_FIRM are pre 4.3 only cards.....just disabling the whitelist would allow any card blocked between 4.5-9.4 to work on 9.4

Understood. Got the full picture now, thanks.

 

[cearp]

I'm sure the 4.5 x

For those who've tried to install old twl_firm: have you tried looking at lgy.log?

I have an idea how we can get twl firm working, I think I will get gamesquest1 to test it!

I don't know if it's buried somewhere in the thread or if I just am blind and missing it and it's right in front of me, but I can't find the name of the .cia file. was it ever said and I just missed it?

 

[luney]

When it was actually in this thread it was called "flashcardtimewarp.cia"

 

[Riff89]

thanks, luckily I found it using that website that archives old versions of webpages. in my experience, I didn't need to go to firmware 4.1-4.5 to install the .cia file. just had to make sure the emunand partition wasn't created. I'm on 9.2 and it works great.

 

[tony_2018]

Well this sucks, so in order for me to get this to to work I would now have to downgrade my xl to 4.5, install devmenu to install the cia, then update to 8.1 (because there are no games with 9.x firmware). Am I correct in thinking this way?

Can you create emunand afterwards?

 

[cearp]

sure, why wouldn't you be able to? do you mean if this cia affects the ability to create an emunand? no, it doesn't

 

[Riff89]

I have the .cia file installed and the emunand partition is up and running on my sd card. This works completely fine. As long as the .cia file is installed without the emunand partition being created, the two do not interfere with each other.

If you already have emunand, simply back up your sd card, format the sd card with Panasonic SD Formatter (a google search will bring it up), move your files back onto the sd card, install the .cia file, create the emunand partition, then move your files back onto the card once more.

The whole process could take the better part of an hour depending on how much is on your sd card.

or you can just grab a spare SD card from a camera or something, stick the GW launcher on, boot it up, install cia to sysynand, and put your old SD card back in the 3DS

 

[Riff89]

That would work if you want to take the time to look for another sd card. I simply didn't have another available to me, so I worked with what I have. Took a lot less time than scavenging around for another card.

 

[DrunkenMonk]

cearp Have you or anybody else tried using big red menu to uninstall this? and if so, was it successful? Or is this still permanent?

so yeah it depends on the person, i have plenty of SD cards lying around, so for me that would be much simpler.....but anyone that doesn't have any other SD cards lying around obviously wouldn't find it easier

i tried having a look with big red menu....but it was all a bit messy, not much way of telling what was what ....might have another look at some point

 

[KongsNutz]

There's no way to do this on 9.4 correct?

 

[gamesquest1]

nope, you need to install the cia file, only way to do that atm is on 4.x - 9.2

 

[Riff89]

What's odd is that all these cards websites claim they still support up to the most recent firmware, but the support list in the original post says otherwise. are the companies just lying to make the sale?

 

[bobtheglob101]

I'm not sure if anybody's noticed this.. but this process is indeed reversible by using GW Launcher's nifty restore NAND feature. The GW Blue Card was working when the .cia was installed but as soon as I restored a NAND backup that was done prior to installing the .cia the blue card no longer launched.
