Yarge is an open source (licensed under LGPL) Nintendo Gameboy emulator written in Rust and focused on accuracy and performance.
It includes cycle-accurate emulation of the GBZ80 CPU and PPU FIFO.
The emulator is built on a modular architecture, isolating the core from frontends (which can be used as a regular Rust library).
SDL2 frontend is fully-featured with intuitive UI and various quality-of-life features such as save slots.

yarge-frontend-desktop is no longer actively maintained, but I'm keeping it around because it's debugging capabilities are still much better then those in yarge-frontend-sdl
