+
+# Megafest
+
+The fat manifest for W3D Hub Packager and Launcher(s), represented as a JSON hash.
+
+This **MEGAFEST** is intended to simplify patch generation and distribution by ensuring that
+all the data the Packager and Launcher(s) need can be found in a **single** manifest file.
+
+Speed up application packaging by only needing to scan and checksum the new builds files instead of needing
+to maintain a pristine copy of the previous version to be diffed against.
+
+Reduce the number of requests that the launcher(s) need to make to sort out how to download and
+patch the application.
+
+## Glossary
+
+### File
+
+An individual file on disk.
+
+An individual file as part of a MIX archive.
+
+### Package
+
+A collection of one or more files in a compressed archive for efficiently distributing the application.
+
+> [!NOTE]
+> Packages _MAY_ be compressed using ZSTANDARD (.zst) in the future. Do not assume all packages are zip files.
+>
+> Package names in the megafest include the file extension for this reason.

+# Westwood Renegade MIX Archive
+
+with W3D Hub / Tiberian Technologies alterations
+
+The .MIX archive file format is used by Renegade as _yes_.
+
+> [!IMPORTANT]
+> The MIX format has no notion about directories.
+>
+> Each file name **MUST** be unique.
+>
+> e.g. `data/map.dds` and `data/RA_Under/MAP.dds` have the same base file name
+> and therefore **MUST** raise an error when writing.
+
+> [!NOTE]
+> `io_pos` is the current position on the seek head of the open file
+
+## Reading
+
+* Read [Header](#header)
+    * validate MIME type (`MIX1` or `MIX2`)
+* Jump to io_pos `file_data_offset`
+* Read `file_count`
+* Read array of [`file_data`](#file-data-array)
+* Jump to io_pos `file_names_offset`
+* Read `file_count`
+* Read array of [`file_names`](#file-names-array)
+* Read file blobs
+    * For each file's [`file_data`](#file-data-array)
+        * Jump io_pos to `file_content_offset`
+        * Read `file_content_length`
+* Done.
+
+## Writing
+
+* Write MIME type (`MIX1` or `MIX2`)
+* Jump to io_pos `16`
+* Write file blobs
+    * **IMPORTANT:** Add `-io_pos & 7` padding to io_pos **AFTER** each file blob is written
+    * Save io_pos as `file_data_offset`
+* Write `file_count`
+    * Write array of [`file_data`](#file-data-array)
+    * Save io_pos as `file_names_offset`
+* Write `file_count`
+    * Write array of [`file_names`](#file-names-array)
+        * **IMPORTANT:** Ensure file names are null terminated and DO NOT exceed 254 (+ null byte) characters in length.
+* Jump to io_pos `4`
+    * Write [`file_data_offset`](#header)
+    * Write [`file_names_offset`](#header)
+    * Write [`reserved`](#header)
+* Done.
