These are 5 blocks of 10 bytes each. For each sound there is a 2-byte index, then a 4-byte data size (including padding), then the offset at which the data is stored in the SOUNDS\LEVEL0\SOUND.SEP file. The .SEP data for each sound consists of 32 blank bytes followed by a large number of VAG packets (16 bytes each), the final VAG packet having a terminating bit set. At the very end of the .SEP file is a terminating pair of bytes, FE FF, same as in the .DAT file.

RAW storage is indicated by zero .SEP offsets in the corresponding blocks of the SOUNDS\LEVEL#\SOUND.DAT file. As an example, here is a fragment of SOUNDS\LEVEL1\SOUND.DAT featuring the first .RAW-resident sounds. | ||

Here the .SEP offset field is zero for entries 0xAC, 0xAD, 0xAE and 0xAF, then non-zero for the next four entries, and zero again for the following four. The start of the SOUNDS\LEVEL1\SOUND.RAW file looks as follows | |||

Here AC 00 is the 2-byte index of the sound (the same as in the SOUNDS\LEVEL1\SOUND.DAT and in the corresponding SNDD in level1_Final.dat), then there is the 4-byte data size (also the same as announced in the .dat and .DAT), followed by the same data as in the .SEP (32 zero bytes, then some 16-byte VAG packets, the last packet having a terminating bit set). At the very end of the .SEP file is a terminating pair of bytes, FE FF. | |||
