Coffee GB v2.0.2 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:
Summary
Coffee GB 2.0.2 improves Android navigation and large-directory ROM browsing while strengthening native release packaging and recovery.
Android in-screen menus now cover the library, pause, save states, recent ROMs, ZIP selection, and confirmations, with dynamic rows, predictive/system Back handling, and picker restoration across Activity recreation.
The Swing ROM chooser avoids Windows shell icon lookups, preventing stalls when browsing directories containing thousands of ROMs.
Native release packaging now supports guarded resume and recovery checks, reuses passed release unit-test results, and resolves the Windows Maven launcher reliably.
