Hello! I have the same card and after a very long time of searching and failed attempts, I've finally figured it out! It's available at linfoxdomain(dot)com(/)nintendo(/)ds(/), find 'r4igold.cn' and loof for v1.14b. This is (v1.4). Once you've copied the files onto the root of your memory card...
sorry, beein trying to find this file that's been right in front of me for a month now, only to find broken links, and google to prove that it's completely worthless.
