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 its menu using the L+R+Select+X shortcut in order to save your game.

Note that there are two patches:

1. chrono_msu1.ips for emulators prior to higan v096 and SD2SNES without resume support.
2. 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 the Chrono Trigger Symphony albums (volumes 1 through 3) in FLAC format ().
   1. Extract each album to a sub-directory under this directory with a name similar to Chrono Trigger Symphony Vol X (FLAC) where X is the volume number. For example, volume 1 should be extracted to a folder named Chrono Trigger Symphony Vol 1 (FLAC)
2. Run make_music_pack.bat to create the music pack.
3. Create a copy of your original ROM named chrono_msu1.sfc.
4. 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 know some sites will host the complete music pack in PCM format, I do not endorse them at all.

Original ROM specs

Using higan

1. Launch it using higan.
2. Go to %USERPROFILE%\Emulation\Super Famicom\chrono_msu1.sfc in Windows Explorer.
3. Rename program.rom to chrono_msu1.sfc.
4. Copy manifest.bml and the .pcm file there.
5. Launch the game.

Using on SD2SNES

1. Rename the patched ROM file to chrono_msu1.sfc.
2. Drop the ROM file, chrono_msu1.msu, and the .pcm files in any folder under the root folder of the SD2SNES' SD card. (I really suggest creating a separate folder)
3. Launch the game and voil�, enjoy !
