TMV File Format
TMV files have the following header:
'TMAV' - 4 bytes, header signature samplerate - 2 bytes, word value, playback sample rate chunksize - 2 bytes, word value, audio chunk size per frame compmethod - 1 byte, specifies the compression method (currently only 0) charcols - 1 byte, number of text chars across (currently always 40) charrows - 1 byte, number of text chars down (currently always 25) features - bitfield, reserved for special handling:
The features bitfield was never used.
To get the playback rate of the file, divide the samplerate by the audio chunk size. For example, a samplerate of 22050 divided by an audio chunk size of 735 gives 22050/735=30, so the playback framerate of the file is 30.
For details on the video format, consult 8088 Corruption DAT
The audio format used in 8088 Corruption is simply unsigned, 8-bit PCM played at the rate specified in the header.
