I've changed all the music files on the CD, so I have now high quality action music during the game... Wonder how? You have to replace the files MDATA.300 - MDATA.315 These files are the track for the game. They are all in WAV format, with these settings: Signed, 16 bit, mono, 11025 Hz I have replaced them with the following quality settings: Signed, 16 bit, mono, 44100 Hz I had to chose mono, because the wave files were too big, and didn't fit on the CD. My Rebellion version is 512 MB on CD, so you have room for 170 MB for additional data. The MDATA music files are 22,7 MB. So you have about 200 megs space for new music files. 200 against 22! I think we should use this space ...
