A long time ago I was working on a SWF guide version of the guide.wz2100.net (bodies, propulsions and weapons but not the other stuff). I never actually had it finished, but this got me thinking where it might be and, luck! I found my old FLA file and XML.
The SWF gets the data from the XML file and loads icons from a .\icons\ directory. This means it would be easy to edit once the project is completed as just the data XML and contents of icons would need to be altered. I never bothered to add any weapons other than the machine gun into the XML, but I did add all the bodies and propulsions (only viper and cobra have icons though).
This project will need a lot of work doing to it before it would be worty of going on to the website, and possibly a redesign too, but I think I could manage it once I get some free-time in my life (in a few weeks once some exams, sixth-form inductions and trips are over).
If you like the sound of this I'd be more than happy to help as a little thanks to the community.
Edit: I'll also try to get a preview up fairly soon once I find somewhere to host it.
