3DS "decapping" fundraiser

just thought this may be interesting to any 3ds owners in regards to the current status of the scene

What is chip decapping?

For those that are unfamiliar: the CPU, GPU & DSP all exist on one proprietary SOC design used on the 3DS. Secure information is stored there partly, most likely burned onto the SoC during manufacturing and not readable by any other normal means or from outside of the SoC, in such a way that the secure information there, always stays there. In good design it will never reach the main memory of the 3DS and so sensitive data (like encryption keys or algorithms) stay secure.
Extracting data from a proprietary chip to reverse-engineer it is typically done by decapping it, which is risky business and involves removing the epoxy, delayering the chip and taking high-resolution pictures of every layer to reconstruct logic from the images. Special equipment is used ( SEM / scanning electron microscope ) and it is rarely done outside of a professional context because it is very costly to an average enthusiast ("hacker") and access to equipment and the expertise is hard to realize.
Chip decapping has been used by the "emulation" community to reverse-engineer and recover data from special proprietary chips, such as those in SNES cartridges. It has also been used to to reverse-engineer other hardware to create emulators for other platforms besides the SNES.
hopefully this will give the 3ds scene a kick up the arse

I think if 3DS had homebrew I would have one by now.

REALLY wanna play the Zeldas and Pilot wings in 3D!!

Lets hope this leads somewhere
