Author:

Message:

• Updated to new mach_inject with support for x86
• Updated nib files to 10.2+ format so that future updates to the f-script framework won't break fsa
• Adjusted some code to work with the new x86 mach_inject (sends an additional argument)
• Updates code to work with newer defines in cctools

Location:

trunk/Cocoa/F-Script Anywhere/Source/SCPatch/SCPatchController

Files:

• SCPatchController.cpp (modified) (4 diffs)
• SCPatchLoader.c (modified) (2 diffs)
