Case study

Alley Cat: an annotated DOS executable disassembly

Alley Cat Disassembly is an in-progress effort to turn the DOS game's Ghidra disassembly into annotated NASM x86 assembly. Its source is divided into gameplay, graphics, input, sound and data modules, and progress notes document the MZ header, segment mapping and address translation. The build compares the assembled output with the original cat.exe.
