To play Mega Man X2 or Mega Man X3 on non-original hardware, an emulator or FPGA core needs to know exactly how the Cx4 chip processes instructions. While the logic of the chip can be recreated using code, the chip also contains an internal table.

This Data ROM contains the hardcoded mathematical tables (logarithms and trigonometric arrays) that the hardware samples to accelerate calculations. The cx4.bin file is the exact 3,072-byte (3 KB) binary dump of that data ROM. Without this accurate mathematical data, the games will freeze, crash, or fail to render 3D graphical elements correctly.
