I figured out how to get PKHex working on Linux using Wine and thought I would share my info. I'm on Ubuntu 14.04 64bit using the stock repo version of Wine. First off you have a have a 32bit Wine environment which doesn't seem to be the default if your system is 64bit so you may have to move or delete your .wine directory. All you have to do is run this command to setup Wine WINEARCH='win32' winetricks dotnet40
