Coffee GB v1.7.7 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
