![]() While the code is almost functional, I still have to solve a clock domain crossing problem, which requires more learning of vhdl, fpgas, and FIFOs. Unfortunately the complexity of hardware design and synthesis has prevented me from finishing this device. Jumper wires, soldering iron, and related equipment.I bought one for less than $3 on ebay, it can also be obtained from broken consoles. Initially I created a setup using the following hardware I had available: I don’t need to emulate the whole eeprom, it is often enough to be able to read it (dump its contents and analyze them) and write back modified data or backups. Team Twiizers created a setup which is a full interface but running from an arduino instead of FPGA. A Nintendo DS cartridge savegame dumper (and injector). So I decided to give up on an eeprom emulator interface and go for a simpler and slower but equally useful setup. Speed is the great strength of this attack but, do we really need such facilities? Actually, no. To recall, such an attack gave us access to the savegame data stored in a cartridge’s eeprom, allowed us to modify it in a “live” fashion from a PC, and to feed it to the game rapidly. Interestingly I came to the conclusion that such a setup would be overly complicated for what I wanted to accomplish. The EEPROM emulator interface was the one I highlighted and the one I was working to replicate. In the last post, I explained the different hardware attacks that could be used against the DS and the 3DS hardware. PART2: ARM11 in detail + Exploit a vuln in the ARM9 code Find a 3DS vulnerability that can be triggered from the sandbox + Use a hardware attack on the 3DS hardware to get insight of the software running in 3DS ModeĮxploit such vulnerability (arm11 code execution).Get unsigned code execution on the DS Mode.Use a hardware attack on DS Mode Hardware.Let’s begin with some memes to alleviate the reading A successful example of black-box hacking, reversing and exploiting. In this first part I’ll pave the way to go through the whole exploit chain that leads to native code execution in the ARM11 and ARM9 processors of the Nintendo 3DS. Everything comes to an end, and so does the 3DS series.
