But one in particular that I hadn't posted code too, is my fake game that has a bootable computer, inside the fake game, that is actually reading x86 Boot code that was really compiled with the x86 NASM compiler.

I put my code on some backup hard drive somewhere, so eventually I might post it here on the forums for others. But I wanted to start this thread to see what some of you have done, that and to show off what I have done... although to some of you, its probably nothing special.
