Overview ¶

Package host allows you to create a "host" that emulates a computer system with a 6502 CPU, 64K of memory, a built-in assembler, a built-in debugger, and other useful tools.

Within the host it is possible to assemble and load machine code into memory, debug and step through machine code, measure the number of CPU cycles elapsed, set address and data breakpoints, dump the contents of memory, disassemble the contents of memory, manipulate CPU registers and memory, and evaluate arbitrary expressions.
