Nevermind, I was able to get the WAD file from the Installer itself by searching its “magic word” (00 00 00 20 49 73) with a hex editor. Since it was built with the WAD Tools made by Leathl (because the Encrypted Title Key offset has the string “GottaGetSomeBeer” :lol:), it was fairly easy to know where it ended, because an unencrypted Time Stamp is always included in the footer of the channels created by those tools. In this case, it was “TmStmp1316990711”.
If anyone wants the WAD file, just send me a PM.
