From the developer:
nuBolo is a port of the classic Macintosh network game Bolo, written by Stuart Cheshire. It is not a "clone;" rather, it was developed directly from the Bolo 0.99.7 object code. This means the gameplay is very close to the original. nuBolo uses the same map file format as classic Bolo, and generates game log files that can be viewed with BoloViewer. It has been tested on Macintosh OS X versions 10.3 and higher.
You may want to check out more software for Mac, such as Thief 2X, Ranch Rush 2 Collector's Edition or Jean's Boutique 2, which might be similar to nuBolo b9a.
