Virtualizing IPhoneOS 1.0 | Hackaday

Virtualizing computer systems is nothing new. However, Apple gadgets all the time current challenges. Just ask anybody who has constructed a Hackintosh. At least laptop {hardware} is normally uncovered, however on telephones, the problem is even tougher resulting from mysterious gadgets. [Martijn] managed to reverse engineer the iPod Touch 1G sufficient to run iPhoneOS 1.0 on it and has a number of weblog posts explaining how he did it.
The emulator is the ever-present QEMU. He has emulation for the important {hardware}, together with the cryptographic modules, the {hardware} clock, and the timer, together with reminiscence and show and interface {hardware}. However, Wifi, some USB, audio, the sunshine sensor, and a few graphics {hardware} are nonetheless absent. That doesn’t cease the OS from booting, nonetheless.

The posts give clarification of how the gadget boots, and apparently, the openiBoot venture’s code was useful in figuring the entire thing out. It isn’t good. The keyboard crashes issues, for instance. But it’s a main step simply to get this far. The second publish outlines easy methods to arrange QEMU if you wish to have your personal try at it.
On the one hand, the gadget is simply one other ARM processor, which QEMU handles fairly nicely. On the opposite hand, all of the unusual {hardware} makes it difficult to emulate, reverse engineer, and even restore.
