  I played when I was a kid. I figured out you could just build condos like crazy and make money pause build more, and repeat, get tons of money, build all the way up. But I couldn't figure out how to get people to the top level for that achievement.I'm gonna Google that and see what I got wrong

  First of all, super cool. I have a soft spot for SimTower as well. :)> I didn’t want to do a function-by-function port. First, APIs may be copyrightable - and copying a binary that closely might implicate copyright more than an approach closer to clean-room design. But it was clear that I needed some level of feedback from the ground-truth binary in order to provide a hill for the LLM to climb on the reimplementation.Interesting, but isn't this what, say, the Ocarina of Time reverse engineer port does[1]? I imagine the fact that this hasn't been served a takedown notice from Nintendo is a proof that it's defensible? Or at least that there's precedent, ha.Anyway, this is really cool. I genuinely think the only thing that's missing for me to waste an afternoon here is the sound effects![1]: https://github.com/zeldaret/oot

  Wow!There was a little-known sequel to SimTower called Yoot Tower (named after Yoot Saito). It was a commercial flop, but I played it in the 2000s and again in the 2010s and very much enjoyed it! It had a lot of added customizability (more choices of restaurants and shops, for one thing). I would love to see that game recreated.

  Can you talk about how you actually disassembled the EXE and reverse-engineered it?

  I sunk ages into "the world's most brutal elevator simulator" - how does the game model elevator demand? I always wondered if it was some sort of Poisson distribution.

  Just a fyi for anyone that doesn't know: A few years back Don Hopkins got the permission from Yoot Saito to open source Yoot Tower, SimTower's sequel: https://github.com/YootTowerManagement/YootTower...however I don't think that the source was ever published anywhere, considering that the repository still doesn't have the source code yet. ("Please check out the YootTower repo, where I'll publish the source code once it's cleaned up, reviewed and approved by Yoot, and relicensed with the MIT licensed.")

  I remember that SimTower (Windows 3.1 version) would briefly draw the dialog boxes in Japanese, then immediately redraw it in English. This was on a computer without any Japanese fonts.

  Can you still build a garage in the bottom corner to get more starting money??

  I love SimTower, and one of the reasons I keep my SheepShaver environment working is so I can still play it on Mac OS 9.I’ll have to check this out!

  Oh my gosh, this really brought me back. Haven't played that game in 30 years. What a great use of AI. Thanks for the trip down memory lane.

  Very cool! I used to play this game for a few minutes every morning at a friends place before school. With the clone being open source, would you be open to QoL patches? I don’t have anything specific in mind, just curious how close to the original you want to stay.

  Amazing, loved this game when I was younger. I would keep restarting every time I thought of a more effective layout.I don't think I ever made it to the cathedral though.
