The Mac OS X version of the game (beyond March 31 2005) left over some (but not all) source header files and a precompiled header file in the sounds directory, how exactly the developers did such a mistake is better a unsolved mystery. Multilingual distributions for the game on /depots on Steam have leftover CVS directories from version control for each level in the levels directory, only Entries.extra files have readable data, being just the location of the files. Most likely SignFile is the tool PopCap used to sign most files for their trial wrapper to deter full game cracking. The same file is also present in the original Xbox Live Arcade version on the install disc, but instead referring to different directories and a possible debug build of the game. \bin\SignFile -setsigcode='./ZumaCheat.exe' 'partner.xml' Pushd 'c:\gamesrc\cpp\circleshoot\properties' Present in the Traditional Chinese release is a file called dosign.bat.
