Gameboy by raphamorim review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Gameboy by raphamorim is an open-source Game Boy emulator written in Rust and WebAssembly. It is aimed at developers studying a compact emulator implementation and at users who want to run Game Boy software through a browser, desktop application, or terminal. ROM file loading is supported, and the project includes CPU, memory, GPU, input, and rendering components. Its supported system is Game Boy, with WebAssembly, desktop, and terminal listed as supported platforms.

The project’s strongest differentiator is its range of execution modes and implementation detail. The WebAssembly browser build provides a browser-oriented path, while desktop and terminal rendering offer separate environments for running the emulator. The inclusion of emulation components and a hardware test ROM suite makes the project relevant for examining how a Game Boy emulator is structured and evaluated. According to the project description, the implementation remains under development, and the repository documents hardware-test results with several tests still failing.

Gameboy is open source, so its pricing model is straightforward: there is no paid tier described. The trade-off is feature scope and maturity. The project supports Game Boy rather than Game Boy Color, and the published positioning does not verify save states, link support, or controller support. Choose it if Rust, WebAssembly, multiple rendering modes, ROM loading, and emulator internals matter more than a complete feature set. Choose another emulator if Color emulation, save states, link functionality, or controller support are requirements.
