It’s up at www.supermodel3.com. I assisted with the Linux and OS X support as well as the audio emulation and some last-minute debugging.

UPDATED! Here’s an OS X binary. It should work on at least Snow Leopard and Lion (Intel only). You must have the SDL framework installed in order to run it, and this is a pure command line app, there is no GUI and you must use a Terminal window to run it. (UPDATE: same binary as before, but now includes config file, license, and readme).

UPDATE 2: Here’s an overlay binary that’s explicitly built as 32-bit. This hopefully will run on Intel systems still using Leopard (10.5.x) as well as first-generation Intel Macs that lack x64 support. You want to download and extract the binary above, and then extract this over that – this doesn’t include the necessary files by itself.
