It's amazing that this is possible. I took quite a bit of steering and was definitely not a one prompt endeavor but having a lot of fun with it.

#122Your game looks cool. It's a full, real game! And while I now think that there's no longer strong "platform convenience" reasons to choose any tech stack if these AIs can just bulldoze their way through difficulties, I'm sure running in Godot still made a lot of things easier for it.

#123It's a completely new world. Random retro games I ported to modern webgl/webgpu in the last few months: - The Adventures of Robin Hood - Opus 4.7/Sonnet https://robin.tooclever.org - Syndicate - Sol/Luna 5.6/Opus ( https://this.os.isfine.org/blog/posts/modern-game-port-syndi... ) - Kaiser 2 - Populous Plus - Sol/Luna 5.6/Opus - Dragon Strike - (Fable 5.1 almost one shot) - War of the Lance - Qwnen-3.7-27B-dense (got…
This is amazing. I'm trying to get a handle on how you're doing this, but I can't seem to find anything specific. e.g., is it a case of prompting "Please recreate Populous for the web"?
There's really nothing much to it, all the knowledge needed is in the weights of the model, so regardless of what you want to do, you can ask "if I wanted to do this, what would be the best way / best practices to get there with my machine"

This post has the actual prompt used for one of my ports and the stack, and there's more info below it under "further reading".

1. For each topic, write a result Markdown file in `spec/`.
2. Identify the file formats.
3. Reverse Engineer and extract all assets, followed by manual review. This works in 90% of the cases.
4. Determine the compression/packing used for the executable. Most binaries used one of roughly five common executable packers.
5. Unpack the executable manually.
6. Use an ancient free IDA-Pro for disassembly, or a modified DOSBox to determine all code/data blocks and the relevant segment-register values for the 8086 architecture. In the second case I use my vibe-coded disassembler.
7. Identify the major functional domains in the disassembly and split the files accordingly.

I would like to see all of them :-) One of the most difficult reverse-engineering projects from that era for me was Stunt Car Racer on the C64 (also ported to DOS). It features a highly optimized 8-bit 3D graphics and physics engine. Fable was the first one that was able to generate a complete port of the game. Now I am trying of Flight Simulator 4 and Wing Commander 1. Then maybe Frontier Elite 2. So much fun ....
Strike Commander is in the works. I tried a few months ago and got quite far asset wise but stalled on the flight model, I will probably see how Fable 5.1 does from zero after this weeks limit reset. I imagine it will be able to get quite far.

#128Confirmed in that last paragraph. Just interesting to me I can detect gradations of AI speak at this point.

Which game are you planning to do? We all should coordinate so we're not doing the same games repeatedly.
Ah, it's not going to be Amiga. The shortlist has two PC and two C64 games.

#130It's kind of a fun, albeit also kind of a pointless, thing to do, huh? This week I took a student project game I made with 3 others back in 2010 and made it live again. I'm cheap, I only have the $20 plan for this month (likely to pause again for next month) and used Opus 5, and I'm visibly hamstringing it by running claude code in a firejail and not using yolo mode on permissions. Still, without much effort/oversigh…
