Bundle 2/Burnout Paradise

Bundles are used for nearly every asset in Burnout Paradise, with the only exceptions being the  text file and   binary file (both in the   folder), the non-RAM portion of sound assets, and video files. This makes it one of the most important formats to understand when attempting to parse assets.

While the header contains some valuable data, such as the flags and chunk offsets, the majority of relevant information is in resource entries, which store the ID, uncompressed and compressed size, alignment, relative offset, and type of each resource in each chunk. These also store the import offsets, which enable importing specific data from other resources.

Bundle debug data is also important to understand. Sometimes called Bundle imports, this was originally only available in development builds but shipped with every Bundle in the game in Remastered. Consisting of XML data headed by the  element, it contains the ID, name, and type name of every resource in a respective bundle. This means that effectively every resource name in the game is known. Despite this, the resource names given by the debug data sometimes do not match the hash when encoded. In some cases, such as with Registry resources, this means the name is hardcoded.

Memory types
Across all Bundle versions, a common theme is the use of separate data chunks to define what memory type resources are loaded into. These chunks are platform specific. Keep these in mind when viewing the structures.
