This project is a work in progress. The rk65c02 is a library implementing an emulator of WDC 65C02S CPU. It does not aim to be cycle-exact emulator, but otherwise it tries to mimic behaviour of 65C02S as close as possible. Currently, the following features are implemented:

Emulation of all opcodes, including WDC extensions and BCD mode.
16-bit address space.
Support for interrupts.

The only external dependencies (besides standard C library) are Boehm GC and uthash. On Fedora these can be installed with gc-devel and uthash-devel packages.

If you want to build tests, kyua quality assurance toolkit, atf testing framework and vasm assembler (6502 with std syntax) are also necessary.
