QEMU-iOS

This is a great repo, I am adding an instruction that will fix errors on Apple Silicon macOS Works for M2 Max.

also my syntax for markdown is all messaed up, in order to actually read my instructions it is recommended to download this file and read it in a TextEdit, BBEdit, Etc.

Follow all original instructions VVV double check the authors links down below if errors are present at this point right here directly below in the (())

(( git clone, brew install glib ninja pixman pkg-config sdl2, mkdir build && cd build, ./configure --enable-sdl --target-list=arm-softmmu --disable-capstone --disable-pie --disable-slirp --extra-cflags=-I/opt/homebrew/opt/openssl@3/include --extra-ldflags='-L/opt/homebrew/opt/openssl@3/lib -lcrypto', make -j6))

after running these you should be ready to run, original instructions say "./arm-softmmu/qemu-system-arm -M iPod-Touch,bootrom=,nand=,nor= -serial mon:stdio -cpu max -m 2G -d unimp" we are simply adding a "-display sdl" flag resulting in

./arm-softmmu/qemu-system-arm -M iPod-Touch,bootrom=,nand=,nor= -serial mon:stdio -cpu max -m 2G -d unimp -display sdl

should work fine with that, also ,for controls.. H=HOME, L=LOCK(?), P=POWER(?), Additional(?)

Steps to fix the original iPod 1 emulator linked on here is a little more involved and the instructions are there on my profile. Hope it fixed any issues.

edit, instructions for the iPod/iOS 1g emulator fixes are on this readme, follow below.

after cloning and following all the instructions from orginal author, you might have issues with a few things,

the file at audio/jackaudio.c this edit will be made, this is an improvement to allow both macOS AND linux as the original only allows linux

// Replace this line: pthread_setname_np(*thread, "jack-client");

// With this platform-specific code: #ifdef APPLE pthread_setname_np("jack-client"); #else pthread_setname_np(*thread, "jack-client"); #endif

the file at hw/arm/ipod_touch_sha1.c

// Change this function to accept uint64_t directly instead of void*

static uint64_t swapLong(uint64_t x) {

 // Implement byte swapping for uint64_  

return ((x & 0xFF00000000000000ull) >> 56) | ((x & 0x00FF000000000000ull) >> 40) | ((x & 0x0000FF0000000000ull) >> 24) | ((x & 0x000000FF00000000ull) >> 8) | ((x & 0x00000000FF000000ull) << 8) | ((x & 0x0000000000FF0000ull) << 24) | ((x & 0x000000000000FF00ull) << 40) | ((x & 0x00000000000000FFull) << 56); }

// Then modify the problematic line to:

uint64_t data_length = swapLong(((uint64_t *)s->buffer)[s->buffer_ind / 8 - 1]) / 8;

Also, add

#include <openssl/evp.h>

// Replace the SHA1 calls with:

EVP_MD_CTX *mdctx = EVP_MD_CTX_new();

const EVP_MD *md = EVP_sha1();

EVP_DigestInit_ex(mdctx, md, NULL);

EVP_DigestUpdate(mdctx, s->buffer, data_length);

EVP_DigestFinal_ex(mdctx, s->hashout, NULL);

EVP_MD_CTX_free(mdctx);

The complese section should look like this

uint64_t data_length = swapLong(((uint64_t *)s->buffer)[s->buffer_ind / 8 - 1]) / 8;

if (data_length > 0) {

EVP_MD_CTX *mdctx = EVP_MD_CTX_new();
const EVP_MD *md = EVP_sha1();
EVP_DigestInit_ex(mdctx, md, NULL);
EVP_DigestUpdate(mdctx, s->buffer, data_length);
EVP_DigestFinal_ex(mdctx, s->hashout, NULL);
EVP_MD_CTX_free(mdctx);

}

This will fix the errors, from here you can run make or make -j8

QEMU-iOS is an emulator for legacy Apple devices. Currently, the iPod Touch 1G and iPod Touch 2G are supported.

The schematic below shows the most important hardware components of the iPod Touch 2G and their interactions. The schematic for the iPod Touch 1G is mostly similar.

Running the iPod Touch 1G

Instructions on how to run the iPod Touch 1G emulator can be found here. A technical blog post with more information about the peripherals and reverse engineering process is published here.

Running the iPod Touch 2G

Instructions on how to run the iPod Touch 2G emulator can be found here.
