xbox 360的破解难度太高了。

The flash is encrypted with a per-box key
The key is stored inside the CPU
The boot ROM is stored inside the CPU
Also inside the CPU is a hypervisor that verifies the running state of the kernel, making sure there is no modification (RAM checksums), else the Xbox360 panics and blows up!
The CPU contains RAM inside of it to store the checksums (This is just a speculation by TheSpecialist at the Xbox-Scene Forums)
All interrupt/exception handling is done by the hypervisor
All code runs in kernel mode
The emulator for first generation games can be updated via an official Microsoft download burned to CD by the user, though the CDs' content will be encrypted and signed with public key cryptography.
xbxo 360现在跑clone,其实只是修改了光驱的固件。
和XBOX相比,XBOX 360的保护等级可说是天壤之别。 |
