1. Introduction
AIBO MWC (Middleware Catalog) files are index tables, for associating
the elements/chunks stored in ODA files. Since AIBO stores
Motion, LED & Sound elements separately, it needs a way to know
which elements belong together.
The MWC file tells AIBO which elements go together, and provide
AIBO a reference number called the MWCID. The MWCID can be
used
directly within R-Code to play a skit, using the
PLAY:MWCID:<value> command. Generally though human
readable names are preferable (see Action Config
Files).
Following the header are block & chunk records. Each
block record is immediately followed by its associated variable sized
chunk records (a chunk header plus variable size chunk name).
For example, an MWC file with blocks containing 3, 2, and 1 chunks
in turn:
<header> <block> <chunk> <chunk> <chunk> <block> <chunk> <chunk> <block> <chunk>
|
These files may be optionally GZIP compressed (AIBO can decompress them
on-the-fly).

MWC
Chunk Record
Chunk headers are followed by the variable length chunk name
(length specified by the 'namelen' field below).
struct mwc_chunk_header_type {
char signature[4]; // "CMAC"
int chunktype; // See type codes below.
int repeat_count;
int starttime;
int alwayszero;
short synchronize; // Chunk elements should be synchronized
short special; // Chunk is special system action
char namelen;
};
