We have a few treats for Delphi users in this post:
1. This means we have a “groundwork” to add support for more targets with Delphi:
2. The above “groundwork” already achieves something useful: you can write various 3D and 2D processing tools with the engine on the new platforms. For example, command-line applications, or regular FMX applications that invoke our engine to do some processing (just not using _yet_ our engine for display).
3. [Castle Model Viewer](https://castle-engine.io/castle-model-viewer) (source code [here on GitHub](https://github.com/castle-engine/castle-model-viewer)) compiles now with Delphi (as well as FPC). This improves our ability to test everything, we like to have every part of our engine working with both FPC and Delphi.
4. Thanks to _Adrian Gallero_, our [Delphi design-time packages](https://castle-engine.io/delphi_packages) install our _“Tools → Castle Game Engine”_ menu also in 64-bit Delphi IDE version.
5. Finally, since we’re on topic of Delphi, let’s add that we also fixed compilation of the latest code with [C++ Builder](https://castle-engine.io/delphi#cpp_builder). We had accumulated 2 small bugs since the last time we checked it, see [this GH issue](https://github.com/castle-engine/castle-engine/issues/683). All good now. Thank you _Zatupitel_ for reporting!
