If you make it some sort of bell sound, or beep, or whatever unique sound and put it in place of speech010, you'll know when you hear that sound a unit has died. Here's the process:
1. Download the SFX archive from lubiki
2. Download the tools from there as well, which include soundbanker.exe
3. Extract the SFX, locate the Japanese speech files, and delete the English one there.
4. Put any wave file you want in the folder, and give it the name of the deleted file. So igame010.wav.
5. Run soundbanker in a command prompt (help is included) and point it towards the Japanese file list.
6. Replace the speech_jpn.dat from the game with the file you made.
That's it, you'll have a game without English speech messages in Japanese.
