Coffee GB v2.0.10 is released. Coffee GB is a Gameboy Color emulator written in Java 16 (core) and Kotlin (UI). It's meant to be a development exercise.

Features:
Full support for GB & GBC emulation.
Partial Super Gameboy emulation (borders and palette).
Cycle-exact CPU emulation. Each opcode is split into a few micro-operations (load value from memory, store it to register, etc.) and each micro-operation is run in a separate CPU cycle.
Quite compatible (all the Blargg's tests are passed, although some game still doesn't work)
Rollback-based netplay
MBC1-5 support
Battery saves
Support for zipped ROMs
ROM-based compatibility tests run from Maven

Coffee GB Changelog:
Coffee GB 2.0.10 improves Android lifecycle behavior, platform integration, controls, and system presentation. It also fixes local-netplay persistence and fast-link negotiation, and strengthens Android audio and native-package regression coverage.

Native packages
Linux x86-64, Windows x86-64, macOS x86-64, and macOS Apple Silicon packages are attached and unsigned.
The portable executable coffee-gb-2.0.10.jar is attached.
On macOS, game controllers require a compatible system SDL2 installation; keyboard input and emulation remain usable without it.
