Pipeworks Spigot Engine
History
The Spigot engine appears to have been developed for their second game, Godzilla: Destroy All Monsters Melee (Gamecube, 2002). The June 3rd, 2002 copy of Pipework's Gallery page calls the engine Spigot, confirming the name.
It was expanded and ported to multiple platforms, being used as late as 2012 (Wheel of Fortune for the Wii U) by Pipeworks, and 2014 by external developers (Colossal Kaiju Combat: Kaijuland Battles, by Sunstone Games)

Virtual Machine
Spigot uses a "PWK Virtual Machine", version 3.01 in Wheel of Fortune (2010, Wii). It appears to be used for scripting, and the scripts are contained in matching .pvd and .pvm files.
Debug info
Some games have shipped with debugging information included, allowing for function/class names to be extracted.
Known games with debugging info:
- Wheel of Fortune (2010, Wii)
- Jeopardy (2010, Wii)
- Night at the Museum: Battle of the Smithsonian (2009, Wii)
- Zumba Fitness (2010, Wii)
- Merv Griffin's Crosswords (2008, Wii)
- Gremlins: Gizmo (2011, Wii)
- UDraw Studio (2010, Wii)
- Monster High: Ghoul Spirit (2011, Wii)
- Haunted House (2010, Wii)
Bundle files
A key part of the Spigot engine are Pipeworks bundle files. These contain named, typed, and compressed resources for the game to use.
Bundle files are stored in .bdg files, although some games use alternate extensions, such as .bdx (Wheel of Fortune, 2012, Xbox) or .bd9 (Colossal Kaiju Combat™: Kaijuland Battles, 2014, Windows).
Sometimes there is an accompanying .jnl file, but this doesn't appear to be neccessary, and is more of a log file of the tool used to compile the bundle file.
The bundle file comes in many versions, with the most well analyzed at the moment being v1.20.
Bundle v1.20 format
| Offset | Name | Size | Type | Value/Notes |
|---|---|---|---|---|
| 0 | File signature | 40 | String | "Pipeworks bundle v1.20 (big endian) \x1a\0" |

| 84 | Types offset | 4 | BE Int | Offset to the directory of resource types. |
| 88 | Types length | 4 | BE int | Length of the directory of resource types |
| 92 | Unknown count 1 | 4 | BE int | Multiplied by 16 and added to the resource directory length |

| 100 | Unknown count 2 | 4 | BE int | Multiplied by 8 and added to the resource directory length |
| 108 | Unknown count 3 | 4 | BE int | Multiplied by 8 and added to the resource directory length |
| Offset | Name | Size | Type | Value/Notes |
|---|---|---|---|---|

| Offset | Name | Size | Type | Value/Notes |
|---|---|---|---|---|
| 0 | Data offset | 4 | BE int | Offset to where the resource begins |
| 4 | unknown | 1 | byte | |
| 5 | uncompressed length | 3 | BE int | The length of the resource after decompression (zlib inflate) |
| 8 | unknown | 1 | byte | |
| 9 | compressed length | 3 | BE int | The length of the compressed resource |
| 12 | unknown | 4 | ? | Possibly a resource ID? |
Other software
at least Wheel of Fortune (2010, Wii) has a separate engine called "RockNRoll" which appears to be used for collision/physics.
It also uses the Fonix middleware for speech (recognition or lip-syncing?), and FMOD for audio playback. Videos are encoded in the THP format.
