af6502

6502 8-bit processor emulator

This emulator is still a work in progress.

All opcodes have been implemented, and they were tested individually through unit tests, but no global testing (i.e., running a piece of assembly through the emulator) has been performed yet.

Usage

The emulator shall be operated from the command line.

The command line flags must have space between each other, but their arguments are attached. For example, to load a file and activate the register status output:

af6502 -input=./program.bin -showstatus

Command line arguments:

  • -cycles= (followed by a number, without quotes): sets the number of clock cycles to execute
  • -input= (followed by the path, without quotes): selects the input binary file
  • -showstatus: displays the status of the registers in the terminal, at the end of the execution
  • -dump= (followed by the path, without quotes): selects the path for the memory dump file
  • -start= (followed by a number, without quotes): sets the inital value for the Program Counter register, that is, the starting memory location of the executable. When loading a binary, it will be transcribed to memory starting from this value

Invalid flags are ignored.
