Insert SWF in home page instead of post

I have wordpress flash game website. Into the admin panel, where I add or edit post I have field named Swf URL: where I add SWF link and it links to the post where it shows flash game. I want to do same but not in the post, I want to use this function (adding game with the help of swf) to home page.

How it is now:

How I want to see:

functions code:

[ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]

load_theme_textdomain( "freebabyhazelgames", TEMPLATEPATH."/languages" );
    $locale = get_locale( );
    $locale_file = TEMPLATEPATH."/languages/{$locale}.php";
    if ( is_readable( $locale_file ) )
    {
    	require_once( $locale_file );
    }
    $sp_boxes = array( "Game Details" => array( array( "thumb", "Game image URL:" ), array( "game", "Swf URL:" ) ) );
    add_action( "admin_menu", "sp_add_custom_box" );
    add_action( "save_post", "sp_save_postdata", 1, 2 );
    if ( !function_exists( "get_custom_field" ) )
    {
    	function get_custom_field( $field )
    	{
    		global $post;
    		$custom_field = get_post_meta( $post->ID, $field, true );
    		echo $custom_field;
    	}
    }

<strong>post code:</strong>

    <div id="playgame">
    						<script type="text/javascript">
    						<!--
    						swf("<?php $values = get_post_custom_values("game"); echo $values[0]; ?>", "701", "550");//-->
    						</script>
    					</div>

By the way I tried to change dirrectory or to copy single.php to index.php but both not worked.
