I remember back in the day I would hack on mods for a series of games called Escape Velocity. And these mods were entirely created using resource forks for everything from game logic to flavor text to images. ResEdit was the closest thing we had to an IDE. Compared to source control that would allow us to collaborate, or even SQlite databases that could be trivially backed up, it felt like we could lose our work at any time. But at the end of the day, that was part of the fun.<p>More info on how it worked: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Plug-in_(Escape_Velocity)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Plug-in_(Escape_Velocity)</a> (why this is a relevant article in Wikipedia, I have no idea.)<p>Note to anyone reading this, though: If you&#x27;re designing a system from scratch, don&#x27;t even think about using resource forks to store data. Just say no.
