I've been toying with hbfirmware and it seems that the code provided to load and run the SLOT-1 card do not work. How would I get this to work?
All help is appreciated!

It does work, when it is started at the boot-time.
Slot-1 is not decryptable by normal software means after the boot process is done, and no event has reset the encryption system.

So, in other words, it\'ll only work if it\'s flashed to the DS? If that\'s the case it\'s gonna be a pain to play with. But it does work?
So, would it be possible to load, say, the game icon before while attempting to test my firmware without reflashing my DS? I know that there are the different encryptions for different portions of the card. I think.

The official firmware writes the header of the card to the main ram before passing control: http://nocash.emubase.de/gbatek.htm#dscartridgeheader

So, from what I understand, if hbfirmware were flashed to the DS, it would be able to launch the card, but it cannot run it if it was booted from a Slot-2 card instead, right?
And from what I gather, (I\'m not terribly good at understanding GBATek,) The Icon and Title are outside the encrypted region and would be able to be read just fine, correct?
Thanks for your speedy replies!

Yes, that is how it is supposed to work. As soon the original firmware flags the encryption everything is too late, unless the encryption is reset by an physical event.

Correct.

The icondata and title are encrypted. The only way to reset the DS card is to re-insert it. After re-insertion you can do a decryption procedure, and find the icondata and title.

The problem is just that once the encrypted data has been read, it can't be read again without resetting the card, which requires either removing it or turning the DS off. The BIOS reads it and leaves it in memory for the firmware to find, but all homebrew loaders I know of (as well as the firmware WMB client) remove it for whatever reason.
There's a bunch of info URL removed but I think they require registration to view it, which is annoying. There's some nice code posted there that does all the encryption and stuff for you so you can read the card freely (still has to be reinserted though). It's GPL2-infected, though. >_>

I think to use soft reset to boot the next binary.

I have no idea but to guess that the removed URL pointed at an illegal website, in which case I find it weird that the contents on that illegal website are GPLv2-licensed.

I'm sure there was nothing illegal on that site last I checked. You could find some distasteful things if you signed up and poked around, but not in that thread. Ah, I love it when moderators delete things without any explanation why. -_-

GPL licensing doesn't magically make things legal.
If a site involves making copies of commercial games it should not be linked here.

I'm not the moderator who deleted it. (I'd have been more likely to replace the URL with "PIRACY DOT COM" or the like.) But I'm guessing that "it's not illegal" has little to do with it. This server is private property. Even though the discussion of piracy methods is not necessarily unlawful, the administrators have seen fit to ban links to domains that focus on the discussion of piracy methods.

So is card-reading code considered piracy-related, or was there a thread having something to do with piracy in there that I missed? It doesn't do much good to tell someone "you're breaking the rules" without specifying just what they're doing to break them.
