I have completed a basic compression of the webm files, again attempting to make the changes indistinguishable; I do not notice any quality loss between the original webm and the newly compressed webm. It shaves off about 250mb. I also did a once over and did specific compression parameters for huge gif files that were unnecessarily large.
These changes coupled with converting the gifs to webp makes the Pics folder go from 3.5 GB to 1.7 GB (~50% reduction) with nigh indistinguishable quality loss.
I am posting the download link below, everything works (that I tested) in the html file so you can extract and play/test yourself. Randiel feel free to use my compressed version if you find it acceptable. Do note that I did not view and test every single 1500 gifs that I converted and compressed, so if anyone finds that any of the files seem to be extremely glitchy or is not playing right comparatively to the original version, please let me know so that I can reencode and fix it.
Young Marcus Expanded 0.5 Compressed
In the zip file, there is a compression info text file which lines all of the parameters and processes I did to compress it. This is more for Randiel/anyone else planning to mod this game, but if you have any questions, please let me know!
Also, as an interesting matter of perspective,
The original Young Marcus version 6.0.1 has a file size of 0.9 GB with 1161 files.
The uncompressed version of Young Marcus Expanded v0.5 is 3.5 GB with a whopping 2445 files.
My compressed version of Young Marcus Expanded v0.5 is 1.7 GB with the same 2445 files.
The amount of eye candy and content that has been added to Young Marcus in the expanded edition is simply amazing and I look forward to further development, great job Randiel!
