The original port to vBulletin was not completely legal as it made use of two php-files from the original InvisionBoard-AdminCP.
This is why I am completely redoing the ACP, completely integrated in vBulletin and its style
Of course ibProArcade did not loss any feature and even got improved alot, e.g. most AddOns are already implemented, bugs got fixed ect.
Yes, you can play in PopUp-Windows as an option
Yes, both v3arcade and ibPA-Games will work
Yes, even PNFlashGames should work (have none to test)
Just be patient, it will be worth it
ACP is abouot 65% finished yet, will continue ...
