I love emulators.
They allow me to take a nostalgic trip back in time running software and playing games from yesteryear without leaving the comfort of my current desktop. I can load up WinUAE for example and delve back into my Amiga days playing forgotten classics such as Cadaver, Dreamweb, or Alien Breed. Or fire up Directory Opus and play around with the Amiga OS.
In most cases I don’t even need to run an emulator on my OS as there are plenty of websites that will do that for you. Catering to the retro scene you can play just about any game on a myriad of bygone computer hardware or gaming consoles.
Maybe you are in the pub talking to your mates discussing the video games you played in your youth. You could pull up a YouTube video to show what it looked like, or you could fire up the game via emulation and actually play the game yourself in real time. The power of the internet!
I do love emulators!
Now for a quick game of Galaga..
