# 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.
