> Not only could it display in color, but it also supported scaling and rotation effects. IIRC the Lynx was designed at a time (1986-87) when this was feasible for portable systems but not for consoles, because of its low resolution (160

There is a Game Genie code decoder/encoder here: http://www.smspower.org/maxim/forumstuff/gamegenie.html (This was designed for the Sega Game Gear version, but the Game Boy algorithm is the same.)
