Show HN: HyperCard to HTML Converter

https://github.com/stachon/hc2html
2•druidcz•1h ago
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.
