I loved video games when I was growing up (Aladdin’s Castle anyone?). Now you can play all those old video games on your Mac. All you need is an emulator (the virtual video game console) and ROMs (the virtual video game).
Emulators: Emulator Zone
ROMs: ROM World
The experience gets even better when you buy a USB video game controller. I was able to score a PS2-like controller at Target for only $10.
