Ugh... whatever retard uploaded this has a system that doesn't support Shift-JIS, and they corrupted all the filenames in the central directory of the zip file when they added their shitty advertisement to it.
Thankfully all the individual file headers are in tact, but standard extraction software doesn't use those.
Run this program on the zip file and it'll rebuild the central directory based on the individual headers, thus fixing all the filenames.

Then extract under Japanese locale.
