the instruction is a damn mess.. this will only work for a non-modified arcade.php, since you obviously were too lazy to write proper modification instructions, instead you just threw in the code of your final arcade.php.. which pretty much wrecks all previously applied modifications. probably a decent addon, definitely non-decent instructions.
ps: currently comparing your code with mine, trying to get it in there some way. I noticed this line in the instructions:
Code:
$game = $DB_site->query("SELECT * FROM " . TABLE_PREFIX . "games A, gamescat B WHERE A.categoryID = B.categoryID ORDER BY gameid ");
I think gamescat should include the table prefix, e.g. " . TABLE_PREFIX . "gamescat
