I've rewritten MAWS, which you can find at http://www.ids.ca/mame/maws2.zip It is a stand-alone app, written in Java, so it should run just about anywhere. See the readme file in the zip for how to configure. Currently it loads all data files on start up - so it will be very slow to start and consume a lot of memory. This may result in it not running in constrained environments (e.g. very old computer, raspberry-pi, etc). As a very rough estimate, assume you'll need about 750MB-1GB free RAM.
The coding was done largely without looking at the original MAWS code, so differences may exist. I've attempted to recreate the GUI, based on images from the wayback machine, with some tweaks to make better use of screen real-estate. The current feature set is largely due to BYOAC member feedback, with artwork from 8bitmonk, et al.
