Crystalis is an action role playing game for the Nintendo Entertainment System.

This is a fix for Crystalis having faulty code in its audio engine involving the PCM channel (drumline). It causes an audible / annoying buzz constantly in the music. Once you hear it, you can't unhear it so this is for all the sensitively eared people in the world who also love this game.

• There's an optional patch included to remove the PCM pop (it makes the drum sound much softer)

• There is an audio comparison of the 2 patches in the zip file (the "buzz fix" and the "pop removal + buzz fix") to help you decide which one you want to use.

Note: This is compatible with God Slayer and it's retranslation https://romhacking.net/translations/3793 *but* you have to patch this first BEFORE you patch the translation.
