mpw-emu

An extremely ridiculous weekend project that tries to do user-mode emulation of PowerPC executables for classic Mac OS, to run the CodeWarrior C++ compiler without faffing about with SheepShaver or QEMU.

Features

• Loads PEF executables wrapped in MacBinary format
• Implements enough nonsense to compile object files using MWCPPC from CodeWarrior Pro 1
• Probably won't destroy your file system
• It's written in Rust! 🦀

TODO

• Implement the missing relocations for the PEF linker
• Implement more of the C standard library
  • Figure out a way to make printf better (maybe fork one of the existing Rust implementations)
• Implement more of the Macintosh Toolbox(tm)
• Make the file system bridge more robust
  • Improve detection of type/detector codes
• Check if I can make loading files more robust
  • Should I try to support packed formats other than MacBinary?
  • Using file/..namedfork/rsrc might let me load raw files on MacOS
• Test whether #includeing files works
• Get more MPW executables working
  • Investigate why some of them aren't PEF files (are these XCOFF?)
