You can give a try now, I've uploaded the files to mediafire. You need to edit line 3 in the file join.php, which stores the mysidia adoptables directory in a variable called $mysdir. Change it to whatever fits your site. Replace the join.php in your tcg site with the new one, and add the library file integration.php to the directory mytcg/. This should do the trick.
