Coffee GB
Gameboy emulator in Java 8
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. ... -

Mastermind RK
The classic board game "Mastermind" for various Z80 computers
Mastermind RK is a little cross-platform game for various classic Z80-based computers, written in C using the z88dk compiler (www.z88dk.org). Your goal is to break a four-digit colour code in as few moves as possible. The compiled program is a little over 8K in size, so it usually requires the target machine to have at least 16K RAM. Currently, 83 target systems are supported, including Mattel Aquarius, Sinclair ZX80 and ZX81 (with a separate Chroma colour version), ColecoVision, various Robotron computers, Philips P2000 and VG5000, and many more. 2025-11-10: - New target supported: Commodore 128 (using the Z80 CPU) -

ZAPH
Tools and Z80 engine for creating adventure games. (RUST)
This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools. -

Elite Planet Browser
Browse through the planets of the Elite game on various Z80 machines
First of all: this program is totally useless. But those of you who know and love the classic computer game "Elite" will maybe like it. The "Elite Planet Browser" is a little program for various classic Z80-based computers, written in C using the z88dk compiler (www.z88dk.org). It allows you to browse through the planet data of the Elite game on many old Z80-based computers. When the original game came out in 1984, many people wondered how it is possible to have detailed data of so many planets in the 16K RAM memory of the BBC Micro. ... -

ZxSim
API (C#) for simulating certain aspects of a ZX spectrum for porting.
Initially this project is a showcase of my abilities to write code using C# and DotNet libraries, along with Design Patterns and SOLID techniques. The project itself is a bunch of libraries that make porting Spectrum games easier using C#. Originally I would use a popular UI and write code emulating the Z80. However over time those UIs would come out of favour or not compile on a modern OS, so the first aim is portability. The current examples will use Godot to display and control the game. Next is re-usability, broken up into separate scopes there is a natural layer of usage. Along with all this is some code to handle the original games data and to emulate some of the routines found in the original Z80, such as sprite blitting and room drawing. ... -

cpm-libgsx
GSX functions library for CP/M (...and SDL2 with SDL2_gfx)
This library can be built for either CP/M or UNIX systems. On UNIX systems it depends on the SDL2 library (along with the SDL2_gfx). For CP/M, this library should compile with LLVM's Clang patched for Z80 architecture support. To build test applications you need to link them against CP/M C library (see my other project, cpm-ulibc).
