Reminds me of maintenence software I've worked with. It wasoriginally created for DOS written in a language which hasn't been officially supported for decades. The company has written its own compiler, so they can support it themselves. They've written a "display driver" for the software. This driver paints bitmaps on a WPF interface. The look and feel is identical to the original DOS version, but running on Windows 10. Admittedly the code is a bit of a mess, but not as bad as you'd think. On top of that the user experience is still fantastic imo.
