*** EXPLANATION ***
|
|
|
|
BMA is merely a container. It is very expandable, though the
|
|
file table could definately use a facelift. Have fun.
|
|
|
|
Anything not specified in the file is considered null, and can
|
|
be used for any purpose (considering those area are not read,
|
|
so custom tags could be added after the main header but before
|
|
the file table.)
|
|
|
|
|
|
|
|
*** SOURCE HEADERS AND DEFINITIONS ***
|
|
|
|
Make sure you use these typedefs:
|
|
TypeDef Unsigned Char Int8;
|
|
TypeDef Signed Short Int16;
|
|
TypeDef Signed Int Int32;
|
|
|
|
And constants:
|
|
Const BlockSize = 4096;
|
|
|
|
And these libraries:
|
|
ZLib
|
|
|
|
|

*** FILE ***
|
|
|
|
The file's true offset is at (FileOffsetBlock*BlockSize) in the
|
|
file. If a file is ZLIB compressed, there will be an extra
|
|
string at the end of the chunk, in ASCII, that contains the
|
|
uncompressed file size in bytes.
|
|
|
|
OGG audio is not compressed in these files because they can be
|
|
loaded directly into memory and played by a sound library.
