Think you need to check your references: http://www.b5tech.com/oldb5tech/earthalliance/earthallianceshipsandvessels/earthcapships/omega/omega.html
So is this canon in any kind of way or just some info that fans imagined? Because we never ever see the small guns fire beams in the show! Also who dreamed up all the information of the TBP weapons section anyway
? I mean, I am not a physicist but only a chemist, still anyone knowing only a tiny bit of science knows that a X-Ray laser can't ever be visible. Call it a plasma beam or neutron beam or particle beam or whatever, but not a laser! Was this mentioned on the show somewhere? I know that the Minbari neutron beam was stated on some background screen, but I think on the Babylon 5 Scrolls it was explained that even that wasn't to be taken seriously.
Speaking of the latter, there was some cool info on that site stating that the forward beam guns on the Omegas were supposed to be the two big rectangular sections in the middle, looking exactly like the beam guns on G'Quan cruisers where the EA bought them from, and not the small guns on the sides, which were pulse cannons. Only the mistake of a CGI guy made them use those guns for the beams as well and it seem TBP and the B5 Tech site took that for valid and made it true for all the pulse cannons. Okay, I doubt it is the job of Zathras to fix something like this...
BTW, I know there is another thread for this, but you really need to consider including yellow power beams for Drazi, Centauri and Brakiri into the next Zathras version. I did this in another way than described there now and it looks great! You see, there are separate Drazi beam bitmaps which are in fact copies of the EA files. So I changed them to yellow in Paint.Net and gave them to the Centauri and Brakiri using weapons.tbl. This would be an easy thing to do in Zathras and would make TBP more consistent to the show
