# linker_pc: reconstructing the Call of Duty 4 fastfile linker

> linker_pc reconstructs the fastfile linker distributed with the Call of Duty 4 mod tools from its shipped 2008 executable. The recovered source builds a 32-bit Windows tool that reads zone CSV files and writes .ff fastfiles, using specified MSVC flags to preserve x87 floating-point behavior.
