This file is not just a random piece of data; it is the digitized soul of a specialized coprocessor that Capcom developed to push the SNES beyond its hardware limits. What is cx4.bin? The Capcom Cx4 is a proprietary mathematical coprocessor
The Capcom Cx4 is a proprietary mathematical coprocessor developed by Capcom. It was embedded directly into specific SNES game cartridges to offload complex computational tasks from the console’s central processing unit (CPU). Key Technical Capabilities
The Cx4 chip (short for Capcom Consumer Custom Chip) was a Hitachi HG51B169 DSP (Digital Signal Processor) operating at 20 MHz . It was a unique piece of hardware that Capcom designed to give their games capabilities the standard SNES couldn't easily manage.
