An open-source 2D top-down RPG editor and engine, which aims to support RPG Maker XP projects. It uses Ruby for scripting, and will make attempts to maintain compatibility with existing third party RPG Maker XP scripts.

While not an exact clone, it should be close enough to be comfortable, and more importantly, to just work. There will be additional enhancements and features beyond the original capabilities of the RPG Maker XP engine.

OpenXP is currently in early development. It is not recommended for production use at this time.

At this point we are focusing on interoperability and compatibility with RPG Maker XP projects, both via the editor and a runtime implementation.

The editor is the initial focus. Once the basic functionality is completed, we will change focus to the runtime, which will be based on the previous project OpenGame.exe, but limited to RPG Maker XP support.

Speaking of, the runtime is notably absent for the time being. It is being worked on, and will be merged in at a later time.

More enhanced features will be added in the future.

OpenXP's runtime intends to officially support Windows, Linux, and Mac. It is not yet ready for use on non-Windows platforms. The editor may be made cross platform, this is yet to be determined.

You must own RPG Maker XP in order to use the OpenXP editor, in accordance with the details of this project's license (see License below for more information). I strongly respect the intellectual property rights of others, and while we are using a clean-room approach to implementation, I have no desire to compromise the value or integrity of their product.

Encrypted RPG Maker archives (.rgssad) will not be supported. While the format is publicly known at this point, the copyright holders for RPG Maker XP has directly expressed that it is against their wishes for the encryption details to be investigated or made public. New forms of encryption will be made available for this editor at a later time.

Win32API is not supported. A plugin system is planned that will allow you to extend many facets of both the editor and the runtime, and additionally you have access to the source code to tailor the engine to your needs. A cross-platform runtime is a high priority with this project, and most existing Win32API-dependent scripts will likely not work as intended due to a different backend.

We also use NuGet to manage dependencies- as long as you have package resolution enabled, this process should run automatically and install the required libraries.

Some dependencies are bundled in the repository, where custom built options were preferable.
