The Capcom Cx4, originally a Hitachi HG51B169 digital signal processor (DSP), was a specialized coprocessor integrated into only two retail SNES games: and Mega Man X3 . Its primary purpose was to offload complex mathematical tasks from the SNES's main CPU, specifically handling trigonometric calculations required for wireframe 3D effects, sprite rotation, and scaling.

If you are a fan of retro emulation, particularly Super Nintendo (SNES) emulation on platforms like RetroPie, MiSTer, or modern Snes9x cores, you have likely encountered the requirement for bios files. Among these, you might have seen a file labeled cx4.bin . While many SNES games run without external files, a handful of specialized games require this specific file to function correctly.
