Myst and Riven aren't the only games to use the Mohawk format. In fact, many Broderbund based games use it. Here is a (partial) list of games known to use it:

• Green Eggs and Ham
• In the 1st Degree
• James Discovers Math
• James Explores Math
• Logical Journey of the Zoombinis (aka Zoombinis Logical Journey)
• Maggie's Barnyard Adventure
• The Treehouse
• Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure)
• Where in the USA is Carmen Sandiego?
• Where in the World is Carmen Sandiego? (Windows/Mac version)

Video

All the videos of the original games are QuickTime movies. The later Zoombinis release has Bink videos instead.

The audio codec is raw, signed, 16-bit data in Big Endian format. The video codec, however, is not standard. It has the FourCC 'QkBk' and has description "CDToons". Neither QuickTime nor mplayer/ffmpeg can play this codec and its format is unknown. Some videos still use Cinepak (like "The Chief" videos in Carmen Sandiego).

QSET

This is a question set. This links questions together into sort of like a dialogue tree.

(Big Endian Order)

• count is the amount of values the follow.
• values is an array which is probably a list of QUES/ANSW (need to check).

QUES

This is a question. It appears to hold data for the text as well as the sound clip associated with it.

(Big Endian Order)

• u0 appears to always be 1. Possibly question count?
• sound is the sound clip associated with this question.
• u1 is unknown. Always 0?
• u2 is unknown. Possibly the answer to this question?
• u3 is unknown. It's usually 2.
• u4 is unknown. It's usually 100.
• u5 is unknown. It's usually 100.
• u6 is unknown. It's usually 100.
• u7 is unknown. Always 0?

Common Resources

tBMP

All tBMP resources contain a Mohawk Bitmap.

tWAV

This is a Mohawk Sounds resource. (Found in all but Logical Journey of the Zoombinis)

tPAL

This is a palette. Here's what I've worked out so far. It's tied together with tBMP and tBMH.

(Big Endian Order)

Following that is color_count RGBA quads.

This is found in Where in the World is Carmen Sandiego?, Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure), Green Eggs and Ham, In the 1st Degree, and The Treehouse.

tCNT

Unknown. The data size is always 4 and follows this format:

(Big Endian Order)

resource_id appears to always equal the tCNT that this belongs to.

This is found in Where in the World is Carmen Sandiego?, Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure), James Discovers Math, Green Eggs and Ham, In the 1st Degree, and James Explores Math.

tSCR

Unknown.

This is found in Where in the World is Carmen Sandiego?, Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure), Green Eggs and Ham, and The Treehouse.

STRL

This is a string list.

Following that is string_count NULL-terminated strings. This seems reminiscent of Riven's NAME resources.

This is found in Logical Journey of the Zoombinis, Where in the World is Carmen Sandiego?, and Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure).

tBMH

These appear to also contain a Mohawk Bitmap.

This is found in Where in the World is Carmen Sandiego?, Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure), Green Eggs and Ham, and The Treehouse.

tMID

This is a Mohawk MIDI resource.

This is found in Logical Journey of the Zoombinis, James Discovers Math, James Explores Math, In the 1st Degree, and The Treehouse.

REGS

Unknown.

This is found in Logical Journey of the Zoombinis, Green Eggs and Ham, and The Treehouse.

BYTS

This appears to be able to hold multiple things. In DATABASE.MHK, it holds database entries (one large null-terminated string), but elsewhere it appears to be something else.

This is found in Where in the World is Carmen Sandiego? and Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure).

INTS

Unknown.

This is found in Where in the World is Carmen Sandiego? and Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure).

BBOX

Some sort of boxes? It follows this format:

(Big Endian Order)

And then, it has rect_count rects:

This is found in Where in the World is Carmen Sandiego? and Where in America is Carmen Sandiego? (The Great Amtrak Train Adventure).

ANI

This is found in Maggie's Barnyard Adventure and Green Eggs and Ham.

BITL

In Green Eggs and Ham, it contains these two bytes:

This is found in Maggie's Barnyard Adventure and Green Eggs and Ham.

SHP#

This is found in Maggie's Barnyard Adventure and Green Eggs and Ham.

SYSX

This appears to be a list of Adlib MIDI commands. There are only two resources in Zoombini (which are found in MIDIMAP.DAT) and are 1 or 0xFFFF. They are identical. In the 1st Degree has several more in MIDIMAP.DAT.
