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/early 00'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.

• Billy Frontier

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.
