Pomme: a cross-platform implementation of the Macintosh Toolbox C API

Pomme is a partial, cross-platform implementation of the Macintosh Toolbox C API. It is designed to ease the porting of 90's games written for MacOS 7-9 to modern operating systems. You can think of it as a cross-platform reimagining of Apple's own Carbon, albeit at a much reduced scope.

The goal isn't to achieve 100% source compatibility with old Mac C programs, but rather, to make it a bit easier to port them. I only intend to implement the bare minimum functionality required to keep a reasonable level of source code compatibility with the games I'm interested in porting.

This library was originally written to port Pangea Software's Nanosaur and Bugdom to modern operating systems.

Features

Files and resources:

  • Access files on the host's filesystem with FSSpec structures.
  • Read/write data forks.
  • Access resources inside AppleDouble files (transparently presented as resource forks to application code).

QuickDraw 2D:

  • Load images from QuickDraw 2D PICT resources and files.
  • Manipulate ports.
  • Basic draw calls: lines, rects, bitmap text, CopyBits.

Sound Manager:

  • Load audio from AIFF & AIFF-C files and snd resources.
  • Supported audio codecs: raw PCM, ima4, MAC3, ulaw, alaw.
  • Use SndChannels to output audio thanks to the built-in software mixer (requires SDL).

QuickDraw 3D-ish:

  • Basic QD3D geometry structures and math routines.
  • Load 3D model data from 3DMF files.
  • Please note: Accurate source compatibility with QD3D is out of scope for Pomme. For a faithful implementation of QD3D, look at Quesa.

Misc:

  • Memory management routines.
  • Limited playback of QuickTime moov files (only Cinepak is supported).
  • Byte-swapping routines inspired from Python's struct format strings to convert big-endian structs to little-endian.
  • Basic keyboard/mouse input via SDL.
