Some crazy Japanese modder has come up with this: I think you will all agree that this is an amazing job! He's even gone into detail about the process over 10 pages. In Japanese, of course. http://www.lcv.ne.jp/~mgs1987/sega/gg.html I don't think this has been mentioned before, but apologies if it has!
Even so, It's pretty spectacular, it almost deserves to be re-posted, and perhaps announced from the rooftops.
So be it... *From atop Mount Everest with an amplifier capable of reaching the whole planet* HEAR YE, HEAR YE!!! CHECK OUT THIS AWESOME GAME GEAR CONSOLE!!!
