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.
