Seems to work ok. Game offers an option for slow or fast PC, but even with the fast PC option you need to set cycles low, like cycles=700.
Game launcher offers options for Amstrad PC 1512, Tandy or "other". Regardless of option chosen (with appropriate emulation set) it seems to launch in CGA mode with PC speaker.
This is a game that uses CGA composite, so it is best if you launch it in a CGA composite compatible video mode (e.g. machine=cga).
