Quick description about coffee gb:

Coffee GB is a Gameboy Color emulator written in Java 8. It's meant to be a development exercise. More info can be found in the blog post. First I implemented all the Gameboy CPU opcodes. It�s not exactly the Z80, but it�s pretty close. As a reference, I�ve used the GameBoy CPU Manual - later on I discovered that it has a few typos and is not specific enough for some of the operations. After implementing the opcodes and memory (modelled by an int[] array) I was eager to check whether it�s possible to run some code on it. I had neither the cartridge nor the GPU emulation yet, so even the simplest game wouldn�t be an option. However, when the original Gameboy starts, it executes a simple 256-bytes program, a kind of firmware displaying the Nintendo logo and self-testing the system. That was exactly the thing I was looking for - after just 3 days I had an application running the Gameboy code!.

Features:

• Cycle-exact Gameboy CPU emulation
• Quite compatible (all the Blargg's tests are passed, although some game still doesn't work)
• MBC1-5 support
• Battery saves
• Support for zipped ROMs
• ROM-based compatibility tests run from Maven

Programming Language: Java.
