Hi. I had a lot of trouble with getting the speech and music files to work on Mac OSX but there is a solution! Behold! here's what you do.
1.) In Safari go to Preferences and uncheck "Open "safe" files after download". This will prevent Safari from unzipping the speech and music packs automatically! I think this is the problem most people were having.
2.) Download Speech file. Download 3D0 music file.
3.)Ctrl-Click each zip file and go to "Get Info". Then delete the .zip extension! The extension should be .uqm now.
4.)Follow ReadMe for MacOSX users! [i.e. place uqm files in Contents:Resources:Content:packages!
You know, MIE on Windows does the same thing when manually downloading the UQM files. I had that issue when I ran the installer after downloading the files, it couldn't find the .uqm.zip files that MIE had "helpfully" renamed.
Are these browsers second-guessing the file names based on MIME type? Why are they renaming files without the users' consent? Gah! Such a simple problem but it's obnoxious that it exists at all!
