I own an old Game Gear from the early 90s, and have been curious for years as to why it's such a power hog. It takes six (SIX!!) double-A batteries, all of which can drain within an hour or two of playing.
The original GameBoy only used 4 AA batteries and it certainly did not drain as fast as the Game Gear.
I understand that they are from different companies and used different concepts, but what exactly was the Game Gear doing that used so much power? I know it has color, would that make a difference?
