# Disassembler

6502.Net also provides a simple disassembler via the `disassemble` command. The input file is considered to be machine code, and the output file will be the disassembly of that machine code.

```
~$ dotnet 6502.Net.dll disassemble myprog.prg -o myprog_disassembly.txt
```

By default the program origin is the first two bytes of the input file, as that is the default output format for 6502.Net in asssembly mode. To specify a different format, use the `--format` option.

```
6502.Net.exe disassemble myxexprog.prg -o myprog_disassembly.txt --format=atari-xex
```

Most output formats are supported except the whole disk/tape ones, like `d64` and `t64`.

If the input files are flat (no header or program load address encoded into the file), you can manually specify the program counter with the `--disassembly-start` option. Note this value must be a decimal integer between 0 and 65535. Similarly, if you want to specify the machine language CPU, pass the `--cpu` option.

```
~$ dotnet 6502.Net.dll disassemble myspeccyprog.bin -o myspeccyprog_disassembly.txt --cpu=z80 --disassembly-start=4096
```

Finally, to disassemble the code at a specific offset, you can pass the `--disassembly-offset` option.

```
6502.Net.exe disassemble myprog.prg -o myprog_disassembly.txt --cpu=65C02 --disassembly-start=4096 --disassembly-offset=128
```
