Try this: In arcade.php search for "//get games", right under that is:

       //get games
               $DB->query("select g.*, c.password from ibf_games_list as g
            left join ibf_games_cats as c on (g.gcat = c.c_id)
                  where g.active = 1 ".$show_all.$search.$catselect."
                    order by ".$this->arcade->settings['g_display_sort']." ".$this->arcade->settings['g_display_order']." ".$query_limit);
                while( $this_game = $DB->fetch_row() )
        {
                $games[] = array(	'gid'                =>  $this_game['gid'],
					'gwidth'    =>  $this_game['gwidth'],
					'gheight'   =>  $this_game['gheight'],

change to (parts in red added, don't miss the comma after 'password'):

        //get games
               $DB->query("select g.*, c.password, c.cat_name from ibf_games_list as g
            left join ibf_games_cats as c on (g.gcat = c.c_id)
                  where g.active = 1 ".$show_all.$search.$catselect."
                    order by ".$this->arcade->settings['g_display_sort']." ".$this->arcade->settings['g_display_order']." ".$query_limit);
                while( $this_game = $DB->fetch_row() )
        {
                $games[] = array(	'gid'                =>  $this_game['gid'],
					'cat_name' => $this_game['cat_name'],
					'gwidth'    =>  $this_game['gwidth'],
					'gheight'   =>  $this_game['gheight'],

This should fill in $entry['cat_name'].
