As staindaddict requested, here are the links to the games from my Sendspace Pro account which isn't going to expire any time soon. I will also be submitting these to the audio games archive so they'll have a permanent home if anybody wants them. Hats off and thumbs up and thanks to staindaddict for providing them!
