# Digimon V-Pet: a literate disassembly of the 1997 firmware

> Digimon V-Pet investigates the 1997 Digital Monster firmware, focusing on Ver. 1 and comparing Ver. 2. Static analysis and emulator experiments map its Epson E0C6200 program, RAM, LCD, care and battle behavior, and device link protocol. The repository includes an article, Ghidra maps and tools that generate annotated listings from a user's firmware dump.
