The file responsible for storing your key mappings is controls.rmp located under “C:\Documents and Settings\<your>\Local Settings\Application Data\Electronic Arts\Dead Space”

I discovered not only the offsets storing the Up/Down/Left/Right key mappings but also the correct values for the arrow keys - AND THEY WORK.
