LHCf is a collider experiment dedicated to obtaining information relevant to ultra-high-energy cosmic-ray physics. One of the two LHCf detectors has position-sensitive silicon microstrip layers that are read out with front end electronics. These electronics saturate for high energy photon showers because of the limited dynamic range of the preamplifier. Consequently we are planning an upgrade of the processing circuits in anticipation of LHC operation at increased collision energy, and we are developing an analysis method to correct for the saturation effect. An overview of these data analysis methods will be given in this paper.
