I found the original "The Legend Of Zelda" online and have been re-addicted. It took me a while to get used to using the keyboard instead of a controller, but I have managed to get to level 7 so far.
The day I got this cartridge years ago, we played it for over 24 straight. The Nintendo machine was so hot that you could have fried an egg on it. We were afraid we were going to burn up the machine. What was the coolest part, was when we were finished we were delighted that there was a whole new adventure after the first one. This is a true classic in the game world.
