Description
I created a converter that turns HyperCard 2.x stacks into standalone HTML so they can run in a modern browser.I built it to share my own stacks from the early '90s, which have been sitting on old floppy images for 30 years.It's MIT-licensed and I'd welcome contributions - especially stacks that break the converter, since I've only tested it against my own. If you have old HyperCard files lying around, I'd love to hear how they fare.

Could you build this?
Partial Displaying card UI elements in modern HTML is straightforward, but parsing 30-year-old proprietary Mac binary resource forks and correctly interpreting HyperTalk scripts requires complex format reverse-engineering.
What it would actually take: Requires writing a binary parser for the HyperCard 2.x stack format to extract card layouts, bitmap resources, and background chunks from legacy Mac OS data/resource forks. It also requires an AST parser and JavaScript runtime engine to interpret HyperTalk message-passing semantics in modern browsers. The primary difficulty lies in emulating the quirky behaviors, obsolete text encodings, and edge cases of vintage Apple software.
