sars 4 and i use both melee and caster. I love these ui's and really dont want to have to use another one. But i have no clue at all how or what to do to make them current.
We're currently working on revamping SARS with fixes to the base releases as well as optional downloads.
Please check http://p087.ezboard.com/bsarsworld to keep up with the changes and new releases as they become available.
Version 4.3 is now available at the above link, and we will have it cross posted to here soon i'm sure.
