PopCap Games Signature Files (*.SIG)

[LolHacksRule]

I want to modify the XML and XML.BINs (outside properties, in install dir root and DRM) in PopCap games (preferably, Plants VS Zombies) DRM for computers but these pesky plaintext .sig files are preventing them from being read by the games after modification, modifying back however, doesn't make the check fail, the hash isn't commonly known either, any advice or will someone figure out this hash check? You can find xml.bin samples on this format here: viewtopic.php?f=9&t=9335, plaintext XMLs with the sig files here and xml.bin sigs alone here. These pages: https://github.com/sureandrew/SexyAppFr ... yAppBase.h and https://github.com/sureandrew/SexyAppFr ... ppBase.cpp also talk about the sig files.

Thanks on the views but can I bump? Sigs are unique for specific loaders.
