Teenage Mutant Ninja Turtle 4 : Turtle in Time MSU-1
Version 1.0
by DarkShock

This hack adds CD quality audio to Turtle in Time using the MSU-1 chip invented by byuu.
The hack has been tested on SD2SNES, bsnes-plus 073.1b and higan 094.
The patched ROM needs to be named tmnt4_msu1.sfc.

Note they are two IPS patches:
- tmnt4_msu1_emulator.ips is the one to use for proper volume in emulators.
- tmnt4_msu1.ips is for the SD2SNES

The music pack can be found here: https://www.mediafire.com/?1awa8p3p5c956td
