:large_orange_diamond: This is a fork

Fork of https://gitlab.com/Mr_Goldberg/goldberg_emulator

Feel free to make a PR.


:red_circle:

This fork is not a takeover, not a resurrection of the original project, and not a replacement.
This is just a fork, don't take it seriously.
You are highly encouraged to fork/clone it and do whatever you want with it.

:red_circle:


Compatibility

This fork is incompatible with the original repo, lots of things has changed and might be even broken.
If something doesn't work, feel free to create a pull request with the appropriate fix, otherwise ignore this fork and use the original emu.


Credits

Thanks to everyone contributing to this project in any way possible, we try to keep the CHANGELOG.md updated with all the changes and their authors.

This project depends on many third-party libraries and tools, credits to them for their amazing work, you can find their listing here in CREDITS.md.


How to use the emu

You can find helper guides, scripts, and tools here:

(These guides, scripts, and tools are maintained by their authors.)

You can also find instructions here in README.release.md



<br/>

Compiling

One time setup

Cloning the repo

Disable automatic CRLF handling:
Locally

git config --local core.autocrlf false

Or globally/system wide

git config --system core.autocrlf false
git config --global core.autocrlf false

Clone the repo and its submodules recursively

git clone --recurse-submodules -j8 https://github.com/Detanup01/gbe_fork.git

The switch -j8 is optional, it allows Git to fetch up to 8 submodules

It is adviseable to always checkout submodules every now and then, to make sure they're up to date

git submodule update --init --recursive --remote

For Windows:

For Linux:

Building dependencies

These are third party libraries needed to build the emu later, they are linked with the emu during its build process.
You don't need to build these dependencies every time, they rarely get updated.
The only times you'll need to rebuild them is either when their separete build folder was accedentally deleted, or when the dependencies were updated.

<br/>

On Windows:

Open CMD in the repo folder, then run the following

This will:

On Linux:

Open a terminal in the repo folder (Optional) You can use Clang compiler instead of GCC by running these 2 commands in the current terminal instance

export CC="clang"
export CXX="clang++"

Then run the following

export CMAKE_GENERATOR="Unix Makefiles"
./third-party/common/linux/premake/premake5 --file=premake5-deps.lua --64-build --32-build --all-ext --all-build --verbose --os=linux gmake2

This will:


Building the emu

On Windows:

Open CMD in the repo folder, then run the following

This will build a release version of the emu in the folder build\win\<toolchain>\release
An example script build_win_premake.bat is available, check it out

<br/>

On Linux:

Open a terminal in the repo folder, then run the following

./third-party/common/linux/premake/premake5 --file=premake5.lua --genproto --os=linux gmake2
cd ./build/project/gmake2/linux

(Optional) You can use Clang compiler instead of GCC by running these 2 commands in the current terminal instance

export CC="clang"
export CXX="clang++"

Then run the following

make config=release_x32 -j 8 all
make config=release_x64 -j 8 all

To see all possible build targets

make help

This will build a release version of the emu in the folder build/linux/<toolchain>/release
An example script build_linux_premake.sh is available, check it out


Building the tool generate_emu_config

Navigate to the folder tools/generate_emu_config/ then

On Windows:

Open CMD then:

  1. Create python virtual environemnt and install the required packages/dependencies
    recreate_venv_win.bat
    
  2. Build the tool using pyinstaller
    rebuild_win.bat
    

This will build the tool inside bin\win

On Linux:

Open bash terminal then:

  1. Create python virtual environemnt and install the required packages/dependencies
    sudo ./recreate_venv_linux.sh
    
    You might need to edit this script to use a different python version.
    Find this line and change it:
    python_package="python3.12"
    
  2. Build the tool using pyinstaller
    ./rebuild_linux.sh
    

This will build the tool inside bin/linux


Using Github CI as a builder

This is really slow and mainly intended for the CI Workflow scripts, but you can use it as another outlet if you can't build locally.
You have to fork the repo first.

Initial setup

In your fork, open the Settings tab from the top, then:

Manual trigger

  1. Go to the Actions tab in your fork
  2. Select the emu dependencies Workflow (ex: Emu third-party dependencies (Windows) ) and run it on the main branch (ex: dev).
    Dependencies not created on the main branch won't be recognized by other branches or subsequent runs
  3. Select one of the Workflow scripts from the left side panel, for example Build all emu variants (Windows)
  4. On the top-right, select Run workflow -> select the desired branch (for example dev) -> press the button Run workflow
  5. When it's done, many packages (called build artifacts) will be created for that workflow.
    Make sure to select the workflow again to view its history, then select the last run at the very top to view its artifacts
<br/>

Important note:

When you build the dependencies workflows, they will be cached to decrease the build times of the next triggers and avoid unnecessary/wasteful build process.
This will cause a problem if at any time the third-party dependencies were updated, in that case you need to manually delete the cache, in your fork:

  1. Go to the Actions tab at the top
  2. Select Caches from the left side panel
  3. Delete the corresponding cache
<br/>

(Optional) Packaging

This step is intended for Github CI/Workflow, but you can create a package locally.

On Windows:

Open CMD in the repos's directory, then run this script

package_win.bat <build_folder>

build_folder is any folder inside build\win, for example: vs2022\release
The above example will create a .7z archive inside build\package\win\

On Linux:

Open bash terminal in the repos's directory, then run this script

package_linux.sh <build_folder>

build_folder is any folder inside build/linux, for example: gmake2/release
The above example will create a compressed .tar archive inside build/package/linux/
