Document description

Tetris (NES) uses the same music engine and format as Mother, which is already documented. This addendum to that specification provides the equivalent addresses and tables necessary to apply the format to Tetris to create new music and insert it into the game, or to extract and convert music from the game to other formats.

This work is based on Tetris (USA), file CRC32 6D72C53A, ROM CRC32 1394F57E. The addresses and tables are probably applicable to any romhack based on Tetris USA, though it is unknown whether they are applicable to non-US versions.
