This component is a basic rewrite of the original "games" component. It features DIABLO, DOOM II, and a dosbox interface that gives you numerous other games. You can easily modify it to feature other games that you can embed by changing the arcade.php file to link to them.
I just recently used this component with OSSN 5.6 with out any issue. It should work fine with 5.5.
I have the OSSN Premium Package script version 5.5, and I was wondering if my site will crash if I enable your arcade component on it?
