Chrono Trigger: Chrono Trigger MSU-1

This patch adds support for CD quality audio to Chrono Trigger using MSU-1 chip invented by byuu. So far, it is only supported and tested on BSNES, higan and the SD2SNES flashcart.

If the MSU-1 is not detected, the patch plays the original music, thus the patch works on all emulators (but it is less fun to listen to). Some alteration might happen when running on a emulator or flash cart that doesn't support MSU-1.

Everything to build the audio pack is included in the patch but you have the buy Blake Robinson's Chrono Symphony in FLAC format first, see README for more details.

Chrono Trigger MSU-1
Version 1.1
by DarkShock

This hack adds CD quality audio to Chrono Trigger using the MSU-1 chip invented by byuu.

The hack has been tested on bsnes-plus v073+1, higan 096 and SD2SNES. BSNES 070, 075 is NOT RECOMMENDED, use bsnes-plus v073.

For those playing on SD2SNES, you need to exit to menu using L+R+Select+X shortcut in order to save your game.

Note they are two patches
- chrono_msu1.ips for emulators prior to higan v096 and SD2SNES without resume support
- chrono_msu1_resume.ips for higan v096 and up and SD2SNES with resume support

If you hate the fact that dungeon music restarts at the beginning with no-resume patch, delete chrono_msu1-69.pcm.

================
= Installation =
================
1. Buy Chrono Symphony album in FLAC format (http://www.thechronosymphony.com/). Extract them all to a folder.
2. Run make_music_pack.bat to create the music_pack
3. Create a copy of your original ROM named chrono_msu1.sfc
3. Patch the ROM using Lunar IPS or Floating IPS (http://www.smwcentral.net/?p=viewthread&t=78938)

Please support the original author of the album. I known some sites will host the complete music pack in PCM format, I do not endorse them at all.
