ChatGPT Helps Make Willy Immortal
November 5, 2025
This blog explores how I modified Jet Set Willy on the Tatung Einstein TC-01 to make it easier to play. Combining nostalgia with modern tools, I extracted and disassembled the game’s code, used ChatGPT to identify the logic controlling player lives, and patched it using assembly language to prevent lives from decreasing. The project blends retro computing, digital archaeology, and AI-assisted coding, breathing new life into a 1980s classic while celebrating the enduring charm of early home computing.
