You want a real challenge? Try getting Zaxxon playable on a modern PC. The PC version of Zaxxon was written for the original PC's (8086 running at somewhere around 2 and 4 MHz).
The game will actually launch from Windows, but before you can do anything you've crashed into the first wall 3 times...
As far as PiD goes, I never really could get my bearings in that one. I considered myself lucky if I made it to the second floor...
Basilisk can work with just about any version of the MacOS up through 8.1. The tricky part is getting it installed. If you happen to have a CD for the install, it's fairly simple. Otherwise, you'll probably need at least a Disk Tools disk image.
Fortunately,
Apple's download archive has suitable images available. I recommend digging around in there for a few other interesting goodies. You could even theoretically make a CD from the 7.5.3 disk image set (follow the link above, select your region, then go to Macintosh->System->Older_System->System_7.5_Version_7.5.3 and download all the images, then burn a CD from them in Disk Utility). I'm not sure if that particular one is bootable, but together with a Disk Tools image, you should be able to install it.
The other issue is whether or not the OS X version of Basilisk requires an older Mac's ROM (just about any 68k Mac that can boot to the OS of your choice--except for perhaps the 660a/v and the 840a/v--can supply a donor ROM image; instructions and tools for extracting the image are usually included with Basilisk. Of course, the newer the machine it comes from the better, usually.) If you don't have an older mac that you can get the ROM image from, you'll have to do some digging to find what you need. And as usual, working with ROM images is a very grey area when it comes to copyright issues.
