65C02 Reference

This documentation for the 65C02 is auto generated from the virtual CPU used in the Cerberus 2080tm emulator.

The CPU emulation began as a cycle-exact 6502 with some undocumented instructions implemented.

It is now being extended to correctly emulate a 65C02, with the additional WDC instructions being added over time. As such it may be incomplete, but it reflects the current state of the emulator online.

In the documentation below, undocumented 6502 instructions are highlighted in red, unimplemented instructions in purple.
