This is the latest (2.1.0.9) patch available, contains a bunch of changes to be consistent across all the games in the series.
Contains the JimBond007 patch for the Japanese voices. Just install if after the main game.
Also has an archive which contains updated OST from the Super Arrange album Version, if you want to use it follow the intructions inside the archive, keep in mind you don't need to replace all the OST so just use the ones you like more.
Left in the extras as well this time because why not.
If you like the game, buy it on GOG or Steam, support future releases.
