Virtualizing computers is nothing new. However, Apple devices always present challenges. Just ask anyone who has built a Hackintosh. At least computer hardware is usually exposed, but on phones, the challenge is even harder due to mysterious devices. [Martijn] managed to reverse engineer the iPod Touch 1G enough to run iPhoneOS 1.0 on it and has several blog posts explaining how he did it.
The emulator is the ubiquitous QEMU. He has emulation for the critical hardware, including the cryptographic modules, the hardware clock, and the timer, along with memory and display and interface hardware. However, Wifi, some USB, audio, the light sensor, and some graphics hardware are still absent. That doesn’t stop the OS from booting, however.
What people commonly encounter is that charging speed depends on the charger involved, but even one hundred chargers in parallel won’t speed up this iPhone’s charging rate, so what’s up? First off, the phone’s charger chip and the battery’s BMS will both limit charging current, so for experiment purposes, those had to be bypassed. First attempt was using a hefty DC power supply with the original cell, and, unsatisfied with the lack of fire and still relatively slow charging, [Scotty] decides to up the ante.
