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
