I was messing around with my game gear today while it had all the screws taken out of the case. I noticed that while I was playing a few games(lion king, star wars, and mega man), I was able to make the game gear zoom out. it almost looks like a widescreen view and does have a few artifices on the side of the screen that I'm sure we're not suppose to see.
I made a video of it that you can see here at youtube. Does anyone know what this glitch is doing? Is it going from GG mode to SMS mode? I'll try and track down the glitch, because it does seem to be a helpful glitch if you want to see more of the game with lesser details.
