This is amazing... It shows how far PCs have come that we can emulate a machine that I once lusted after in a browser. On a personal note, can anyone remember what the name is of an Amiga game that I once saw at a store? I just remember that there were objects arranged I think in a grid, and there were laser beams, and you could rotate small mirrors on the grid to reflect the beams onto objects, I guess to destroy them. I only played it for a couple of minutes but I'd like to see it again. I remember being amazed at the Amiga's graphics (I had a C64), and I'd love to see how dated they are now.
