[quote name='evilmax17'][quote name='cdeener']Damn that Lynx was huge if you had small hands I feel sorry for you. What is the deal with the speaker being in between the buttons.[/quote]
Usually only the bottom 2 buttons were used. The Lynx had the ability to be played normally (horizontally), but you could also turn the system sideways and play the games vertically on the lengthened screen (vertical shooters mostly). In that case, one set of buttons would act as the Dpad.[/quote]
Don't forget there was also the abilty to invert the screen and flip the controlls so that left handers could be comfortable. Thus both sets of buttons were active. I don't recall any games that used the buttons as a D-pad. Since the design allowed the screen orientation to be done however the player preferred there wasn't any need for that.
A game played in portrait mode could have its controls flipped just as readily as one in landscape mode, so the D-pad in Gauntlet III, for instance, could be at the top or bottom as the player chose.
