GaBber

A Game Boy Advance emulator, written in C++.

Features

• Built-in debugger
• Questionable emulation accuracy
• Professional, ImGui-based user interface

On a more serious note, this was made as a hobby project and turned into a thesis. GaBber is not meant to be better than any of the already existing emulators, but a fun side-project.

Compiling

The following libraries are required to compile GaBber:

• GLEW
• SDL2
• fmt
• soxr

GaBber uses CMake as it's build system, out of tree builds are preferred. After cloning the repository, you may have to initialize the Git submodules like so:

git submodule init
git submodule update

Alternatively, clone with the --recurse-submodules flag.

To compile GaBber, run the following:

mkdir build/ && cd build/
cmake ../
make

The built executable is automatically copied to the repository root.

Usage

Before running, make sure that a valid bios.bin is located in the current directory.

./GaBber <path-to-rom>

Debugger

The debugger can be toggled at any time via the key combination SHIFT+TAB. Emulation is paused when opening the debugger, but can be resumed again by pressing F5. The F3 key can be used to execute to the next instruction.

Development

GaBber uses clang-format for code formatting. After making any changes, please re-run clang-format on the modified files.
