Claude rebuilt the 1989 game 'Prince of Persia' by reusing the original's own code

Anthropic says the Claude Opus 5.5 model rebuilt the 1989 game Prince of Persia, and the notable part is how it worked: instead of writing new logic to draw rooms, it kept the routine the original DOS release already used. Anthropic calls this a checkable example of long-context coding, holding a decades-old, unfamiliar codebase in view and making coherent choices across it.
