Back when I had vB 3.0.x I used ibProArcade, but I didn't like all the IPB coding crap that came with it. So when I upgrade to vB 3.5.x I installed v3arcade and used a hack that converted the games and scores.
I like v3arcade more than ibProArcade, since the version I used had a crappy admin interface. Looking forward to the new released of v3arcade that will be released in 2 days.
