YA6S is Yet Another 6502 Simulator, impelemting a cycle-accurate WDC 65C02S microprocessor. It includes simulated RAM, ROM, and a 16550-compatible UART. It provides a set of interfaces that can be implemented to provide additional types of devices to the simulated system. All 65C02S instructions are supported, and YA6S succefully passes the widely-used functional tests provided by Klaus Dormann.
