Sorry for lack of updates, just got married, so you can imagine my off line life has been crazy...
I'm working on a template update for futureal, for version 2.1 which would of been out sooner, if I wasn't doing the above... life in respects to all that is now slowing down, so over the next day or some I'm working out some of the template fixes I have been doing for futureal then hope to have those files out to him so he can release 2.1.
How stable is it? well from testing I can tell you that the .sql install is a breeze

really cuts the install time down, and I haven't found any major bugs yet. Just some graphical stuff which I've been fixing to hopefully make the arcade scripts match your custom styles better. Or thats the goal..
futureal has really done a nice job up the over upgrade of Proarcade v2.1
