Wow, I went rhough a slight Ecco thing a few weeks ago. I was watching a play through of Ecco on DC. I still have nightmares of this time I spent a good 2-3 hours climbing up a wall of wells. I made it to the top, paused the game, went to make a cup of tea and knocked the power plug just a touch, but enough to disconnect the power to my megadrive. Super sad.
It was a UK MD, so I had an adapter to get it running. Sigh. So sad
