...The project was created with the goal of improving both accuracy and speed compared to earlier emulators, achieving a balance that allows games to run reliably even on lower-end systems. It supports not only Game Boy Advance titles but also Game Boy and Game Boy Color games, making it a versatile multi-generation emulator. The architecture is written in C and focuses on precise hardware emulation, including CPU timing, graphics rendering, and audio output, which are essential for compatibility with a wide range of games. It includes multiple frontends such as Qt for a full graphical interface and SDL for lightweight usage, giving users flexibility depending on their environment.
