initial version
The [[Hollywood]] includes an ARM9 core, nicknamed the Starlet. This is a very interesting piece of hardware, as it basically does everything that makes a Wii different from a Gamecube.

== Hardware ==
* arm926ejs (or similar) core.
* AES and SHA-1 hardware engines
* Boot ROM
* OTP key/hash area
[[Starlet Register List]]
== Tasks ==
The Starlet handles at least these tasks in the Wii
* NAND access / filesystem
* DVD subsystem
* Code decryption and signature checking
* Disc decryption
* USB HCD
* USB Keyboard driver
* USB Ethernet driver
* WiFi
* TCP/IP
* SD card
* RSA encryption / decryption / signing / verifying / etc
* Sensor bar
* Probably handles the Audio/Video encoder I2C bus as well
== Boot ==
Starlet is the first processor to run code in the Wii.
* Starlet boots from an internal Mask ROM, BOOT0
* BOOT0 decrypts, verifies, and runs the first few blocks of NAND, BOOT1
* BOOT1 locates, loads, decrypts, verifies, and runs BOOT2
* The BOOT2 bootstrap then loads the embedded ELF file.
* BOOT2 starts the IOS.
At some point, Starlet loads code into an EXI buffer and bootstraps Broadway.
== Links ==
More information about the Starlet:
* [[IOS]] - the OS that runs on the Starlet and handles calls from the Broadway during game execution and while in the system menu.
* [[ARM Binaries]] - the formats used for Starlet executable code
* [[WAD Files]] are used for BOOT2 and the IOS
