Unable to play these games because the archive is corrupted. I don't get why the end part is .zip.001 because I can't even open up the zip file. Also, I have 2 files for Windows and I don't even know which one is which.
There are some instruction on the download page for how to join the archive. Because the total size is 3GB, it has been split into 2 separate downloads. Open the .001 with 7-zip.org/download.html and extract the files. The .002 data will be unarchived automatically.
