You put "http://4dsbrew.org" instead of "http://4dsdev.org/" in the change log.

I'm also still getting some debug prompts like "aes key ZERO"

It shows up during the health/safety screen.

I will verify that my BIOS dumps include all the keys... I must have missed one...

I'm simply getting a black bootrom error screen:

no$gba doesn't appear to like the sdmmc code used in sudokuhax I get
"notyet supported sd/mmc command 00000000"
"notyet supported sd/mmc command 00000008"
"notyet supported sd/mmc command 00000037" <-|
"notyet supported sd/mmc command 00000029" --| loops these last two over and over

Look like if I don't use my WIFI-DSI.BIN it works properly

You can also probably dump them using an IS-TWL-DEBUGGER as that seems like a full jtag debugger.

For SD Card emulation, does somebody know a utility for creating empty SD/SDHC Card images (with MBR and FAT)?
A .zip with several empty SD/SDHC Card images (with different sizes) would be nice, too.
For testing, I would currently need some small image with 16MB or so. But bigger images with more MB or GB might be also useful at some point.

Hmmmm, aside from the raw image, I would also need to have (or create) the ID/capacity info stored in CID, CSD, OCR, SCR registers. Preferably with authentic values that could be also found on real SD/SDHC cards with same capacity.
I am afraid that there's no utility (or dataset) for getting that values, or is there something... maybe in another emulator that emulates SD cards?

The other option would be dumping the SD card image AND the CID/CSD/etc from real SD cards. I have some 128MB, 1GB, 2GB, 4GB cards around - so I could dump those cards.
The advantage would be getting real authentic values. The disadvantages would be not getting clean/empty images (if the original card wasn't empty).
And, when releasing no$gba with SD Card support, it would appear quite foolish to prompt users to create the SD card image "by dumping a real SD card".

Would be nice, but probably very difficult to find somebody who has the required hardware & software & knowledge on using it - for at least confirming if ROM dumping is possible or not. But yeah, would be great if somebody could check that!

You could use dd and parted to make a formatted disk image from scratch.

That tools are available for windows?
If not: no$gba is a dos/windows utility, so prompting users to install linux for creating no$gba sd-card-images would be a bit weird ;- )

I've meanwhile dumped the MBR, FAT, and CID, CSD, OCR, SCR registers from my 128MB SD card, so I've at least some values to start with - and could probably modify them to simulate other SD card capacities (and hope to get that right).

Btw. I've been always wondering if it's possible to use more than one SD card.
For MMC cards, multiple cards are handled via the ALL_SEND_CID command (CMD2): Upon that command, the card with the smallest CID number is switched to "ident" state (and any other cards stay in "ready" state until sending futher CMD2's).
For SD cards, CMD2 does exist too. But the public SD card specs appear to refuse to mention if it's supporting multiple SD cards in same fashion as for MMC. But just came across this datasheet, http://www.altec-cs.com/downloads/Produkte/Flash_Speicherkarten/SD_Cards_miniSD_microSD/SanDisk_SD_Card_I-G_PM_1.0.pdf - which says "The host repeats the identification process (i.e., the cycles with CMD2 and CMD3 for each card in the system)." It doesn't really say WHAT happens upon CMD2, but it sounds as if CMD2 might be actually working as on MMC.
Did anybody ever try such a thing? Would be interesting if it's working technically (although I doubt that the DSi firmware/games support it). I'll need to gather components for making some SD/MMC Y-cable.

I *might* be able to make a stack that makes a directory act like a FAT partition.

DeSmuME already does that... so he could look at how that works and re-implement it.

Posted by nocash

Yeah, something like that is planned - sooner or later. At the moment I am focusing on getting the SD card CMD's and ACMD's working (and stick with a SD card image for now).

And creating a "virtual" SD card image from a directory: The creation wouldn't be too difficult.

Creating a "full" image (with actual data files in it) would be probably quite slow, so I would prefer to create only the FAT+directory (and keep the actual data file at their original locations) (ie. using some list that tells which "cluster" is in which file, and at which file offset).

The problems would be handling changes to the files...

The first issue would be if the file gets changed on the PC (by some other application). I guess one couldn't do much against that(?) or would it be possible (and desired) to "lock" all files in the directory?
Otherwise one could just tell the users not to touch the files during emulation.
Or maybe trap timestamp changes and force the emulator to eject-recreate-reinsert the SD card.
Any ideas how to handle that? Or info how DeSmuME is doing it?

And the other issue would be handling changes by the emulator: Changing/adding/deleting files, and somehow reflecting that changes to the directory when the emulation stops.
Or maybe even instantly reflecting it upon any changes to FAT or directory, so a file would get instantly deleted in the directory when the emulated software is deleting it in the SD image.
