a) At the time it was impossible for me. I think I could actually do it now. But now that I can read the BASIC... what would be the point? If I wanted it cross platform, I will build a virtual machine. b) Claude Code has performed exceptionally well. I haven't tried the most recent Codex update. But I don't see the point in spending thousands of dollars on tokens to rewrite it when it works perfectly fine. It would be much cheaper to have Claude Agent build the virtual machine. That's just my opinion. If it ain't broke don't fix it I guess. I do want to bring it to mobile though, whether that's a phone app or responsive website.
Can the original code simulate the stock market as it operates today? The main reason I would want to convert the engine to a modern language is to make it easy enough to understand that I could add features.
