Just so you guys know, Dosbox Staging 0.75 and beyond (on all operating systems) fully emulate Stargunner correctly. Please refer to the link below:

Dosbox Staging v0.75.0 Showcase - Stargunner (1996) - Youtube Video
DOSBox has had dynamic recompilation support for a long time, but it was limited to 32-bit builds. Support for 64-bit dynarec improves CPU emulation speed and quality across the board - this is especially visible to Linux and macOS users
Before 64-bit dynarec, Stargunner had serious emulation problems resulting in fluctuating emulation speed (sometimes too fast, sometimes too slow - regardless of cycles settings). This game was designed to run with constant 70FPS and now it runs with constant 70FPS.
The latest full release, as of this post, is Dosbox Staging 0.79, available for Windows, Linux, and Mac OS-es.
