joevt 11e0bd79b0 debugger: Work around Xcode Terminal.app issue.
If debugging with Xcode using Terminal.app for the console, Terminal.app may send empty lines to the dingusppc debugger while resizing the Terminal.app window and it will do this forever.
As a workaround, use std::cin.clear() to clear the input buffer before getline and loop until the terminal window size is not changing or the input line is not empty.

DingusPPC

Written by divingkatae and maximumspatium

Be warned the program is highly unfinished and could use a lot of testing. Any feedback is welcome.

Philosophy of Use

While many other PowerPC emus exist (PearPC, Sheepshaver), none of them currently attempt emulation of PowerPC Macs accurately (except for QEMU).

This program aims to not only improve upon what Sheepshaver, PearPC, and other PowerPC Mac emulators have done, but also to provide a better debugging environment. This currently is designed to work best with PowerPC Old World ROMs, including those of the Power Mac 6100, 7200, and G3 Beige.

Implemented Features

This emulator has a debugging environment, complete with a disassembler. We also have implemented enough to allow Open Firmware to boot, going so far as to allow audio playback of the boot-up jingles.

How to Use

This program currently uses the command prompt to work.

There are a few command line arguments one must enter when starting the program.

-r, --realtime

Run the emulator in runtime.

-d, --debugger

Enter the interactive debugger.

-b, --bootrom TEXT:FILE

Specifies the Boot ROM path (optional; looks for bootrom.bin by default)

-m, --machine TEXT

Specify machine ID (optional; will attempt to determine machine ID from the boot rom otherwise)

As of now, the most complete machines are the Power Mac 6100 (SCSI emulation in progress) and the Power Mac G3 Beige (SCSI + ATA emulation in progress, No ATI Rage acceleration).

How to Compile

You need to install development tools first.

At least, a C++20 compliant compiler and CMake are required.

You will also have to recursive clone or run

git submodule update --init --recursive

This is because the CubeB and Capstone modules are not included by default. All other components are already included in the thirdparty folder and compiled along with the rest of DingusPPC.

For example, to build the project in a Unix-like environment, you will need to run the following commands in the OS terminal:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make dingusppc

You may specify another build type using the variable CMAKE_BUILD_TYPE.

For Raspbian, you may also need the following command:

sudo apt install doxygen graphviz

Testing

DingusPPC includes a test suite for verifying the correctness of its PowerPC CPU emulation. To build the tests, use the following terminal commands:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPPC_BUILD_PPC_TESTS=True ..
make testppc

Intended Minimum Requirements
