Dynasty Warriors 4 Beta/Pre-Release OST - Struggle For Existence

This is a rip from the recently released PS2 pre-release copy of Dynasty Warriors 4 JP. The disc contained many early prototype or unfinished songs. I'm only uploading the ones that are different from the final release, as there are some in the disc that are identical.

Noticeable differences:
Main guitar is different (more electric-sounding, not as tinny?)
Background guitar around 1:20 is different as well
The background guitar that follows the tune around 1:50 is different; in the final version, the loop is identical (a note is inserted at the end that causes it to line up properly) but in this version it's "off by one" which makes it sound really weird
The solo part is entirely different 2:13
The quiet part around 3:26 has a much louder synth and plays the guitar riff twice instead of only once
The flute solo part around 3:43 has a much stronger echo in it
The guitar solo section after the flute solo is entirely different at 4:07 (different guitar recording? or maybe just differently mixed?)
In the final version, it ends with a quiet single-guitar section before looping back into the main song. This is completely abscent from this one, and it just loops right back into the main song after the section following the solos.
