OpenRW
Recreation of the classic Grand Theft Auto III game executable
...By re-writing the engine from scratch under a permissive, community-friendly license (GPLv3), OpenRW ensures long-term preservation, mod-friendliness, and better hardware compatibility (modern GPUs, controllers, cross-platform input, etc.). For developers, it also offers tools such as a “script tracer” to inspect in-game scripts opcode by opcode, a data-file viewer (RWViewer) for studying object data, models, and map files. -

Defold
Free game engine for development of desktop, mobile, and web games
Defold is an open-source, cross-platform game engine originally developed for 2D games but also capable of 3D — intended to give developers a turnkey solution for building games for desktop, mobile, web, and even consoles. It ships as a full editor/IDE, combining scene editing, asset management, scripting, and build/export pipelines, so developers don’t need to assemble disparate tools themselves. Game logic is written in Lua (with optional native extensions in C/C++ when needed), and the engine uses a component-based system and a message-passing paradigm to manage object interactions — a design that promotes loosely-coupled, reactive game code rather than traditional heavy OOP. Defold is optimized for efficiency: exported games tend to have small binary size and low memory use, making it appealing for mobile, HTML5/web, and lightweight games. -

OpenTK
The Open Toolkit library is a fast, low-level C# wrapper for OpenGL
...OpenTK provides several utility libraries, including a math/linear algebra package, a windowing system, and input handling. OpenTK is not a game engine, nor does it try to be one: It offers a useful set of tools and lets you decide how to use them. It is the ideal starting point if you want to write a game or scientific application from the ground up. The OpenGL specification specifies exactly what the result/output of each function should be and how it should perform. It is then up to the developers implementing this specification to come up with a solution of how this function should operate. ... -

ZxSim
API (C#) for simulating certain aspects of a ZX spectrum for porting.
...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. These will be broken into small plug-in classes which will allow future changes to use PNGs for the graphics instead of simple pixel drawing. ... -
