I really wish I'd had this tool six months ago when I was designing a GUI program for macOS 9. I wanted to import pictures from my modern laptop to a PowerBook Duo and vice versa. Converting all the assets was a pain, and I think this tool would've been incredibly convenient, even just for previewing the images.

The program existed six months ago. That said, currently it only allows to render old QuickDraw pictures on a modern Mac OS X. A tool going the other direction would be simple for bitmaps (just use PNG) or very complicated for vector data.

One thing I'm thinking about making a tool that uses old codecs to make compact images for 68K machines. Basically, use today's CPU power to make efficient road-pizza images.

Offtopic but which tools and resources would you recommend to get started with MacOS 9 GUI development?

I’ve experience with WinAPI/MFC but the classic Macintosh API is quite different and I’d often run into hangs when trying to run simple hello world-ish C++ programs compiled with CodeWarrior.
