Subtract 65248 from the ordinal value of each character. In other words:

$str = "Game some other text by ヴィックサ";
$str = preg_replace_callback(
    "/[x{ff01}-x{ff5e}]/u",
    function($c) {
        // convert UTF-8 sequence to ordinal value
        $code = ((ord($c[0][0])&0xf)<<12)|((ord($c[0][1])&0x3f)<<6)|(ord($c[0][2])&0x3f);
        return chr($code-0xffe0);
    },
    $str);

This will replace all of the "Fullwidth" characters with their normal width equivalents.
