Universal Disassembler program for 8-bit microprocessors
This is a simple disassembler for various 8-bit microprocessors. It reads a binary file specified on the command line and produces a disassembly. It requires Python 3. It has been tested on Linux but should work on any platform that supports Python. See the source code for more details.
The following CPUs are either supported or planned to be supported:
CPU Status
6502 done
65816 done
65C02 done
6800 done
6801/6803 done
6809 done (incomplete)
6811 done
8080 done
8085 done
8051 done (incomplete)
Z80 done
F8 possible
1802 done
TMS9900 possible
usage: udis.py [-h] [-c CPU] [-n] [-a ADDRESS] [-i] filename
positional arguments:
filename Binary file to disassemble
optional arguments:
-h, --help show this help message and exit
-c CPU, --cpu CPU Specify CPU type (defaults to 6502)
-n, --nolist Don't list instruction bytes (make output suitable for assembler)
-a ADDRESS, --address ADDRESS Specify decimal starting address (defaults to 0)
-i, --invalid Show invalid opcodes as ??? rather than constants
