I’ve also been playing around with reverse engineering, and I’m very impressed. It turns out that Codex with GPT-5.2 is better at reverse engineering than Claude.

For example, Codex can completely reverse-engineer this 1,300-line example [0] of a so-called C64-SID file within 30 minutes, without any human interaction.

I am working on a multi-agent system that can completely reverse-engineer C64 games. Old MS-DOS games are still too massive to analyze for my budget limit.

Oh, interesting. I started using the ReVa/Ghidra MCP server together with Claude since day 1 (Well, since Claude Sonnet 4.0 was released) and I saw Claude get better at it with every update. I've gotten pretty far in reverse engineering a game from the early 2000s (though I still have to do a lot of things manually, but this then also taught me A TON about Ghidra)

I'm very interested in trying out Codex now.
