New DSi BIOS/NAND/firmware dumper
I have been updating the DSi BIOS dumper, to hopefully make DSi mode more accessible. It is now able to dump all the files you need for DSi emulation: NAND, DS-mode firmware, BIOSes.

This dumper is also a tad smarter: it will warn you if the data required for proper augmented BIOS dumps has been altered. By the way, the dumps should now be correct-- there was a bug in the previous dumper, where some of augmented bits were read from wrong addresses, although these particular bits don't seem to be important.

The NAND is dumped with a 'nocash footer' (small data block holding the eMMC CID and console ID, required for decryption) added at 0xFF800.

The dumper will place the dumped files in a folder named dsidump, rather than dumping them in your SD card's root.

You can get it here: DSi dumper

I will also redesign the downloads page as to feature a tools section with this, among others.

Dumb question, but can one do this via the 3DS using a DS(i) flashcard / TWiLight Menu++?

I'm not positive it would work for everything, but you can try out.

Is this software to turn DSi ware roms into playable games for melonDS? Or is it a tool to get games from the DSi to the computer?

Has any progress been made on the texture cache in the last couple years?

Interested in texture replacement and I read that melonds would need a "proper" texture cache first a couple years ago.

Sorry, I'm a noob about the 3ds, but to my experience, if there is dsi firmware on it, rather than only settings data, it must be limited. I'm convinced of this because you have to use DS firmware to enable wpa2 lacking wi-fi features (I used hotspot). However, I don't know if it secretly is there, or if you can use it using dsiware, which is a different case.

Can it be used on a DS or a DS lite throut the GBA slot?

the GBA slot isn't going to make the original DS grow a DSi firmware

Flashcards run in DS mode 99% of the time, if someone wants to try this on the 3ds please run it as a DSiWare or trough TWiLightMenu or another DSi homebrew menu.

Also this is a stupid question but this can't dump the protected area of the DSi bios right?
Arisotura says:

it can't, indeed. for now there is no known way to dump the protected BIOS regions.
