While AMS works on Mac OS X up to version 10.12 - both on Intel and PowerPC versions of the operating system - the code currently won't compile on MacOS Mojave. Unfortunately, there's still a lot of work to be done. Applications are launched from the command line for now and are executed by the emulation software, which interprets the system and firmware calls. A version of the project, downloadable from Github, includes a 'Welcome' screen application (a sort of Mac OS 'hello world'), Mac Tic-Tac-Toe, and an animation of NyanCat. He showed me an early attempt at getting the game LoadRunner to work with the emulator - it's not yet interactive.

I got a demo of AMS from Juran at Shmoocon in Washington, DC, this past weekend.

But AMS uses a set of software libraries that allow old Mac applications to launch right within the operating environment of the host device, without needing to have a full virtual hardware and operating system instance behind them. Other emulators out there for 64000 Mac applications such as Basilisk II require a copy of MacOS installation media - such as install CDs from Mac OS 7.5 or Mac OS 8. Advanced Mac Substitute is an effort by long-time Mac hacker Josh Juran to make it possible to run old Mac OS software (up to Mac OS 6) without a need for an Apple ROM or system software. An anonymous reader quotes a report from Ars Technica, written by Sean Gallagher: Want to be able to run classic Mac OS applications compiled for the Motorola 68000 series of processors on your ever-so-modern Mac OS X machine? Or maybe you'd rather run them on a Raspberry Pi, or an Android device for that matter? There's an emulation project that's trying to achieve just that: Advanced Mac Substitute (AMS).
