Build instructions for Emulator (Unix port)

First clone, initialize submodules, install Pipenv and enter the Pipenv shell as defined here. Do not forget you need to be in a pipenv shell environment!

Dependencies

Install the required packages, depending on your operating system.

• Debian/Ubuntu:

sudo apt-get install scons libsdl2-dev libsdl2-image-dev

• Fedora:

sudo yum install scons SDL2-devel SDL2_image-devel

• OpenSUSE:

sudo zypper install scons libSDL2-devel libSDL2_image-devel

• Arch:

sudo pacman -S scons sdl2 sdl2_image

• NixOS:

Build

Run the build with:

make build_unix

Run

Now you can start the emulator:

./emu.py

The emulator has a number of interesting features all documented in the Emulator section.

Building for debugging and hacking in Emulator (Unix port)

Build the debuggable unix binary so you can attach the gdb or lldb. This removes optimizations and reduces address space randomization. Beware that this will significantly bloat the final binary and the firmware runtime memory limit HEAPSIZE may have to be increased.
