The Nintendo 3DS utilizes a dual-core architecture (and a quad-core architecture in the "New" 3DS models). It features an ARM11 processor, which handles the user interface, games, and applications, and an older ARM9 processor, which manages security, encryption, and backwards compatibility with the Nintendo DS.

In early 2018, a hardware hacker known as (with contributions from others like nedwill and plutoo) made a monumental breakthrough. Using a low-level glitching attack (specifically, a voltage fault injection attack known as "the DSiWare glitch" combined with an intricate understanding of the 3DS’s memory layout), they managed to extract the entire BootROM 9 from a physical 3DS console. The Nintendo 3DS utilizes a dual-core architecture (and
The boot9.bin file is a backup dump of the firmware from a Nintendo 3DS, which serves as the "root of trust" for the system's security. This file contains the foundational RSA public keys and cryptographic functions used by the ARM9 security processor during early system initialization. The Role of Boot9.bin How to Get Your Own Copy In early
Once the OS is verified and ready to load, the Boot ROM executes a write-protection command that hides itself from the system. It locks its own memory space so that software running later cannot read the keys.
