Command-Line Tools
6502 Disassembler
A 6502 disassembler with both linear and recursive-descent modes. Decodes the 256 documented + undocumented opcodes, supports labels, and includes Apple II soft-switch comment annotations. Reusable on any 6502 binary, not just Apple II.
nibbler
Python toolkit for analysing Apple II WOZ disk images — from raw flux data to annotated 6502 assembly source in eight commands.
Z-80 Disassembler
A Zilog Z-80 disassembler covering all 256 unprefixed opcodes. CB/DD/ED/FD prefix bytes emit raw-byte placeholders. Reusable on any Z-80 binary — written for Microsoft SoftCard CP/M BIOS analysis but with no SoftCard-specific dependencies.
