Warlords II Deluxe version clarification (2.2.0 vs 2.2.5)

Hi,

you've got two disc images for the game here - v2.2.2 and v2.2.5

Version 2.2.2 is about 737 MB uncompressed because it includes both the data track and the audio track (high quality music).

Version 2.2.5 is about 97 MB uncompressed because it includes only the data track.

My question is, was the disc image for v2.2.5 properly dumped? Did the original CD not come with an audio track? I've installed this game and played for about 5-10 mins, and surprisingly, I can still hear music despite it being such a small size. How is this possible? Did they include all or only a few songs from v2.2.2? Also, oddly enough it says v2.2.6 in-game.

Unfortunately, it seems there are no official patches that allow you to patch to v2.2.5. So if you are using v2.2.2 as your base install, the maximum you can patch up to is v2.2.4.

The difference between v2.2.4 and v2.2.5 according to the readme on the disc:

Clearly, some useful gameplay fixes are mentioned here.

Are there any unofficial patches that let you patch from v2.2.2 (or v2.2.4) to v2.2.5 ?
