Hack description

Tetris 2 + Bombliss is a Japan-exclusive port of Tetris to the Nintendo Entertainment System. It features the classic Tetris mode and a variant called Bombliss.

The explosion sample used in the Bombliss game modes was recently discovered to be corrupted due to an encoding issue known as bit-reversal. This hack corrects the sample and adjusts its length parameter to prevent unrelated data from being played back.

Why not play with the PCM samples sounding as they were intended to?
