This project contains multiple tools for reverse-engineering classic Mac OS applications and games.
The tools in this project are:
- General tools
- resource_dasm: a utility for working with classic Mac OS resources. It can read resources from classic Mac OS resource forks, AppleSingle/AppleDouble files, MacBinary files, Mohawk archives, or HIRF/RMF/IREZ/HSB archives, and convert the resources to modern formats and/or export them verbatim. It can also create and modify resource forks.
- libresource_file: a library implementing most of resource_dasm's functionality.
- m68kdasm: a 68K, PowerPC, x86, and SH-4 binary disassembler. m68kdasm can also disassemble some common executable formats.
- m68kexec: a 68K, PowerPC, and x86 CPU emulator and debugger.
- render_bits: a raw data renderer, useful for figuring out embedded images or 2-D arrays in unknown file formats.
- replace_clut: remaps an existing image from one indexed color space to another.
- assemble_images: combines multiple images into one.
- dupe_finder: a tool for finding duplicate resources across multiple resource files.
- Decompressors/dearchivers for specific formats
- hypercard_dasm: disassembles HyperCard stacks and draws card images.
- decode_data: decodes some custom compression formats (see below).
- render_sprite: renders sprites from a variety of custom formats (see below).
- icon_unarchiver: exports icons from an Icon Archiver archive to .icns (see below).
- Game map generators
- blobbo_render: generates maps from Blobbo levels.
- bugs_bannis_render: generates maps from Bugs Bannis levels.
- ferazel_render: generates maps from Ferazel's Wand world files.
- gamma_zee_render: generates maps of Gamma Zee mazes.
- harry_render: generates maps from Harry the Handsome Executive world files.
- infotron_render: generates maps from Infotron levels files.
- lemmings_render: generates maps from Lemmings and Oh No! More Lemmings levels and graphics files.
- mshines_render: generates maps from Monkey Shines world files.
- realmz_dasm: generates maps from Realmz scenarios and disassembles the scenario scripts into readable assembly-like syntax.
- Install Netpbm (http://netpbm.sourceforge.net/). This is only needed for converting PICT resources that resource_dasm can't decode by itself - if you don't care about PICTs, you can skip this step. Also, this is a runtime dependency only; you can install it later if you find that you need it, and you won't have to rebuild resource_dasm.
- Install zlib, if you somehow don't have it already. (macOS and most Linuxes come with it preinstalled, but some Linuxes like Raspbian may not. If your Linux doesn't have it, you can
apt-get install zlibg1-dev.) - Install CMake.
- Build and install phosg (https://github.com/fuzziqersoftware/phosg).
- Run
cmake ., thenmake.
This project should build properly on sufficiently recent versions of macOS and Linux.
resource_dasm is a disassembler for classic Mac OS resource forks. It extracts resources from the resource fork of any file and converts many classic Mac OS resource formats (images, sounds, text, etc.) into modern formats.
Examples:
-
Export all resources from a specific file and convert them to modern formats (output is written to the <filename>.out directory by default):
./resource_dasm files/Tesserae -
Export all resources from all files in a folder, writing the output files into a parallel folder structure in the current directory:
./resource_dasm "files/Apeiron ƒ/" ./apeiron.out -
Export a specific resource from a specific file, in both modern and original formats:
./resource_dasm "files/MacSki 1.7/MacSki Sounds" ./macski.out --target-type=snd --target-id=1023 --save-raw=yes -
Export a PowerPC application's resources and disassemble its code:
./resource_dasm "files/Adventures of Billy" ./billy.out./m68kdasm --pef "files/Adventures of Billy" ./billy.out/dasm.txt -
Export all resources from a Mohawk archive:
./resource_dasm files/Riven/Data/a_Data.MHK ./riven_data_a.out --index-format=mohawk -
Due to copying files across different types of filesystems, you might have a file's resource fork in the data fork of a separate file instead. To export resources from such a file:
./resource_dasm "windows/Realmz/Data Files/Portraits.rsf" ./portraits.out --data-fork -
Create a new resource file, with a few TEXT and clut resources:
./resource_dasm --create --add-resource=TEXT:[email protected] --add-resource=TEXT:[email protected] --add-resource=clut:[email protected] output.rsrc -
Add a resource to an existing resource file:
./resource_dasm file.rsrc --add-resource=TEXT:[email protected] output.rsrc -
Delete a resource from an existing resource file:
./resource_dasm file.rsrc --delete-resource=TEXT:128 output.rsrc
This isn't all resource_dasm can do. Run it without any arguments (or look at print_usage() in src/resource_dasm.cc) for a full description of all the options.
resource_dasm can convert these resource types:

Notes:
*0: Produces a 32-bit image if a corresponding monochrome resource exists
(ICN# for icl4/8, icm# for icm4/8, ics# for ics4/8, kcs# for kcs4/8). If
no monochrome resource exists, produces a 24-bit image instead. All
color information in the original resource is reproduced in the output,
even for fully-transparent pixels. If the icon was originally intended
to be used with a nonstandard compositing mode, the colors of fully-
transparent pixels may have been relevant, but most modern image viewers
and editors don't have a way to display this information.
*1: The hotspot coordinates are appended to the output filename. As in *0,
resource_dasm faithfully reproduces the color values of transparent
pixels in the output file, but most modern image editors won't show
these "transparent" pixels.
*2: resource_dasm implements multiple PICT decoders. It will first attempt
to decode the PICT using its internal decoder, which usually produces
correct results but fails on PICTs that contain complex drawing opcodes.
This decoder can handle basic QuickTime images as well (e.g. embedded
JPEGs and PNGs), but can't do any drawing under or over them, or
matte/mask effects. PICTs that contain embedded JPEGs or PNGs will
result in a JPEG or PNG file rather than the format specified by
--image-format (which is BMP by default). If the internal decoder fails,
resource_dasm will fall back to a decoder that uses picttoppm, which is
part of NetPBM. There is a rare failure mode in which picttoppm hangs
forever; resource_dasm gives it 10 seconds to do its job before killing
it and giving up. If picttoppm is not installed, fails to decode the
PICT, or is killed due to a timeout, resource_dasm will prepend the
necessary header and save the data as a PICT file instead.
*3: Text is assumed to use the Mac OS Roman encoding. It is converted to
UTF-8, and line endings (\r) are converted to Unix style (\n).
*4: Some rare style options may not be translated correctly. styl resources
provide styling information for the TEXT resource with the same ID, so
such a resource must be present to properly decode a styl.
*5: RMF archives can contain snd resources that are actually in MP3 format;
in this case, the exported sound will be a .mp3 file. Otherwise, the
exported sound is an uncompressed WAV file, even if the resource's data
is compressed. resource_dasm can decompress IMA 4:1, MACE 3:1, MACE 6:1,
A-law, and mu-law (ulaw) compression.
*6: JSON files from SoundMusicSys SONG resources can be played with smssynth
(http://www.github.com/fuzziqersoftware/gctools). The JSON file refers
to the instrument sounds and MIDI sequence by filename and does not
include directory names, so if you want to play these, you'll have to
manually put the sounds and MIDI files in the same directory as the JSON
file if you're using --filename-format.
*7: Tune decoding is experimental and will likely produce unplayable MIDIs.
*8: For color table resources, the raw data is always saved even if it is
decoded properly, since the original data contains 16-bit values for
each channel and the output image file has less-precise 8-bit channels.
*9: icns resources are decoded into many different file types depending on
the contents of the resource. For subfields that have split alpha
channels (that is, the transparency data is in a different subfield),
resource_dasm produces an original image and one with transparency
applied. Some icns resources also contain metadata, which is exported as
.bin, .txt, and .plist files, except for the Icon Composer version used
to create the file, which is ignored. If you want the result in Icon
Composer format, use --save-raw=yes and resource_dasm will save it as a
.icns file.
*A: These resources appear to have a fixed format, with a constant sample
rate, sample width and channel count. You may have to adjust these
parameters in the output if it turns out that these are configurable.
*B: The disassembler attempts to find exported functions by parsing the jump
table in the CODE 0 resource, but if this resource is missing or not in
the expected format, it skips this step and does not fail. Generally, if
any "export_X:" labels appear in the disassembly, then export resolution
succeeded and all of the labels should be correct (otherwise they will
all be missing).
*C: Some coprocessor and floating-point opcodes (F-class) are not
implemented and will disassemble with the comment "// unimplemented".
*D: Most PowerPC applications have their executable code in the data fork.
To disassemble it, use m68kdasm (example above).
*E: The output image format can be specified using --image-format. The
default output format is bmp (Windows bitmap); other supported formats
are png and ppm.
If resource_dasm fails to convert a resource, or doesn't know how to, it will attempt to decode the resource using the corresponding TMPL (template) resource if it exists. If there's no appropriate TMPL, the TMPL is corrupt, or the TMPL can't decode the resource, resource_dasm will produce the resource's raw data instead.
Most of the decoder implementations in resource_dasm are based on reverse-engineering existing software and pawing through the dregs of old documentation, so some rarer types of resources probably won't work yet. However, I want this project to be as complete as possible, so if you have a resource that you think should be decodable but resource_dasm can't decode it, send it to me (perhaps by attaching to a GitHub issue) and I'll try my best to make resource_dasm understand it.
resource_dasm transparently decompresses resources that are marked by the resource manager as compressed.
The resource manager compression scheme was never officially documented by Apple or made public, so the implementation of these decompressors is based on reverse-engineering ResEdit and other classic Mac OS code. In summary, resources are decompressed by executing 68K or PowerPC code from a dcmp or ncmp resource, which is looked up at runtime in the chain of open resource files like most other resources are. (In practice, the relevant dcmp/ncmp is usually contained in either the same file as the compressed resource or in the System file.) There are two different formats of compressed resources and two corresponding formats of 68K decompressors; resource_dasm implements support for both formats.
resource_dasm contains native implementations of all four decompressors built into the Mac OS System file. Specifically:
- dcmp 0 (DonnDecompress) works
- dcmp 1 (a variant of DonnDecompress) is not tested
- dcmp 2 (GreggyDecompress) is not tested
- dcmp 3 (an LZSS-like scheme) works
resource_dasm has built-in 68K and PowerPC emulators to run non-default decompressors. These emulators can also run the default decompressors, which are included with resource_dasm. Current status of emulated decompressors:
- System dcmp 0 works
- System dcmp 1 is not tested
- System dcmp 2 is not tested
- System dcmp 3 works
- Ben Mickaelian's self-modifying dcmp 128 from After Dark works
- FutureBASIC (probably) dcmp 200 works
There may be other decompressors out there that I haven't seen, which may not work. If you see "warning: failed to decompress resource" when using resource_dasm, please create a GitHub issue and upload the exported compressed resource (.bin file) that caused the failure, and all the dcmp and ncmp resources from the same source file.
Run sudo make install to copy the header files and library to the relevant paths after building. After installation, you can #include <resource_file/IndexFormats/ResourceFork.hh> (for example) and link with -lresource_file. There is no documentation for this library beyond what's written in the header files.
The library contains the following useful functions and classes:
- AudioCodecs.hh: MACE3/6, IMA4, mu-law and A-law audio decoders
- DataCodecs/Codecs.hh: Decompressors and compressors for some common and custom data formats
- Emulators/M68KEmulator.hh: 68000 CPU emulator and disassembler
- Emulators/PPC32Emulator.hh: PowerPC CPU emulator, assembler, and disassembler
- Emulators/X86Emulator.hh: x86 CPU emulator and disassembler
- ExecutableFormats/...: Parsers for various executable formats
- IndexFormats/Formats.hh: Parsers and serializers for various resource archive formats
- Lookups.hh: Indexes of some constant values used in multiple resource types
- LowMemoryGlobals.hh: Structure definition and field lookup for Classic Mac OS low-memory global variables
- ResourceDecompressors/System.hh: Decompressors for standard resource compression formats
- ResourceFile.hh: Loaded representation of a resource archive, with decoding functions for many types
- ResourceTypes.hh: Constants representing many common resource types
- TextCodecs.hh: Mac OS Roman decoder
- TrapInfo.hh: Index of Classic Mac OS 68K system calls
Using m68kdasm is fairly straightforward. Run m68kdasm --help for a full list of options.
Currently m68kdasm can disassemble these types of data:
- Raw 68K, PowerPC, x86, or SH-4 code
- PEF (Classic Mac OS PowerPC executable) files
- DOL (Nintendo Gamecube executable) files
- REL (Nintendo Gamecube library) files
- PE (Windows EXE/DLL/etc.) files
- XBE (Microsoft Xbox executable) files
- ELF files
m68kdasm can also assemble PowerPC, x86, and SH-4 assembly into binary.
Some of these formats support CPU architectures that m68kdasm does not support; if it encounters one of these, it prints the code segments as data segments instead.
m68kexec is a CPU emulator and debugger for the Motorola 68000, 32-bit PowerPC, and x86 architectures. I often use it to help understand what some archaic code is trying to do, or to compare the behavior of code that I've transcribed to a modern language with the original code's behavior. For use cases like this, you generally will want to set up one or more input regions containing the data you're testing with, and one or more output regions for the emulated code to write to.
Perhaps this is best explained by example. This command is used to execute the encryption context generation function from Phantasy Star Online Blue Burst, to compare it with the same function as implemented in newserv:
./m68kexec --x86 --trace \
--mem=A0000000/2AC43585C46A6366188889BCE3DB88B15C2B3C751DB6757147E7E9390598275CC79547B2E5C00DD145002816B59C067C \
--mem=A1000000:1048 \
--load-pe=files/windows/pso/psobb.exe \
--pc=00763FD0 \
--reg=ecx:A1000000 \
--push=00000030 \
--push=A0000000 \
--push=FFFFFFFF \
--breakpoint=FFFFFFFF
The --mem options set up the input regions; the A0000000 region contains the encryption seed (0x30 bytes) and the A1000000 region will contain the generated encryption context when the function returns. The --load-pe option loads the code to be executed and --pc tells the emulator where to start. (By default, it will start at the entrypoint defined in the executable, if any is given; here, we want to call a specific function instead.) The --reg option sets the this pointer in the function to the space we allocated for it. The --push options set the function's arguments and return address. It will return to FFFFFFFF, which has no allocated memory, but we've also set a --breakpoint at that address which will stop emulation just before an exception is thrown.
Since we used --trace, the emulator prints the registers' state after every opcode, so we can trace through its behavior and compare it with our external implementation of the same function. When the function returns and triggers the breakpoint, we can use r A1000000 1048 in the shell to see the data that it generated, and also compare that to our external function's result.
render_bits is useful to answer the question "might this random-looking binary data actually be an image or 2-D array?" Give it a color format and some binary data, and it will produce a full-color BMP file that you can look at with your favorite image viewer or editor. You can also give a color table (.bin file produced by resource_dasm from a clut resource) if you think the input is indexed color data. If the output looks like garbage, play around with the width and color format until you figure out the right parameters.
Run render_bits without any options for usage information.
Sometimes in the course of reverse-engineering you'll end up with an image that has the right content and structure, but the colors are completely wrong. Chances are it was rendered with the wrong color table; to fix this, you can use replace_clut to map all of the image's pixels from one colorspace to another.
Run replace_clut without any options for usage information.
Some games store large images split up into a set of smaller textures; assemble_images can programmatically combine them into a a single large image again. Run assemble_images without any options to see how to use it.
dupe_finder finds duplicate resources of the same type in one or several resource files.
Run dupe_finder without any options for usage information.

decode_data can decode and decompress a few custom encoding formats used by various games. Specifically:
Game/App/Library | Encoding | CLI option | Notes
-------------------------------------------------------------
DinoPark Tycoon | LZSS | --dinopark | %0
DinoPark Tycoon | RLE | --dinopark |
Flashback | LZSS | --presage | %0
MacSki | COOK | --macski |
MacSki | CO2K | --macski |
MacSki | RUN4 | --macski |
PackBits (compress) | PackBits | --pack-bits |
PackBits (decompress) | PackBits | --unpack-bits |
Pathways Into Darkness | Pathways | --unpack-pathways |
SoundMusicSys | LZSS | --sms | %0
Notes:
%0: Although these are all variants of LZSS (and are indeed very similar to
each other), they are mutually incompatible formats.
decode_data can be used on its own to decompress data, or can be used as an external preprocessor via resource_dasm to transparently decompress some formats. For example, to use decode_data for MacSki resources, you can run a command like resource_dasm --external-preprocessor="./decode_data --macski" input_filename ...
render_sprite can render several custom game sprite formats. For some formats listed below, you'll have to provide a color table resource in addition to the sprite resource. A .bin file produced by resource_dasm from a clut, pltt, or CTBL resource will suffice; usually these can be found in the same file as the sprite resources or in the game application. Run render_sprite with no arguments for usage information.
Supported formats:

Notes:
$0: render_sprite can't tell from the contents of the resource whether it is
color or monochrome, so it assumes the resource is color if you give a
color table on the command line. If decoding fails with a color table,
try decoding without one (or vice versa).
$1: These games contain some color and some monochrome graphics. It should
be obvious which are which (usually color graphics are in a separate
file), but if not, you can give a clut anyway in these cases and
render_sprite will ignore it if the image is monochrome.
$2: These sprite formats contain multiple images, so render_sprite will
produce multiple image files.
$3: Resources of this type can contain embedded color tables; if you're
rendering a color image that doesn't have a color table, you'll have to
provide one via a command-line option. If the resource (or individual
images therein) contain their own color tables or are monochrome, no
color table is required on the command line, and any provided color
table via the command line will be ignored.
$4: You can get DC2 sprites from the DC Data file with
`resource_dasm --index-format=dc-data "DC Data"`.
$5: The graphics files contain resources that refer to segments of the data
fork in the same file. So, this option expects the original Graphics or
BW Graphics or Persia file (with both data and resource forks present),
not an already-extracted resource.
$6: shap resources contain 3D models and 2D top-down projections of them.
When given a shap resource, render_sprite produces an STL file and an
OBJ file for the 3D model, and an SVG file for the 2D top-down view.
$7: Some XMap resources are stored inside CBag archives. You can extract
them with `resource_dasm --index-format=cbag <CBAG_file.bin>`.
$8: This game has only one clut and it's huge - far longer than the usual
256 entries. It seems PPSS image sets are meant to be rendered with a
subset of this clut, but I haven't been able to figure out (yet) how the
game chooses what subset of it to use.
$9: The game doesn't contain any color tables. You can use a 256-color clut
resource from the Mac OS System file, or use the --default-clut option.
$A: The game stores its sprites in normal PICT resources with an incorrect
type. Use `resource_dasm --copy-handler=PICT:%89%E6%91%9C` to decode
them instead of using render_sprite.
icon_dearchiver unpacks the icons in an Icon Archiver (by Alessandro Levi Montalcini) archive to .icns. Run it with no options for usage information.
- For Blobbo maps: use resource_dasm to get the PMP8 and Blev resources from Blobbo, then use render_sprite to convert PMP8 128 into a .bmp file, then run
