I downloaded a couple of games from this site last night. I got Loom and a few others.
It took me a while to get Loom to work. It worked, but without sound.
Apparently, there is a program called DosBox. You run dosbox.exe and pass it the name of the program you want to run as a parameter. It's kind of interesting, but it worked, and I got sound.
Amazing how simple that game is, andhow small (like 2 megs). I think the biggest game I downloaded was like 6 megs.
And the FAQ for the site talks about the legality of this stuff. Basically, it says that it's not technically legal, but that the copyright holders aren't producing or supporting the software anymore, and thus have no legal reasons to fight it. So, it's legal by virtue of laziness. Interesting.
And some of the games on the site are actually for sale, like Monkey Island, which I tried downloading, but didn't want to pay $14.95 for.
