I bought my nephew the Worms Open Warfare 2 for Nintendo DS game for Christmas. I had a quick play on it myself and couldn't work out how to pan over the landscape - he has a DS lite which doesn’t have the l/r buttons to activate the pan function. Is there a way to overcome this problem? Have I been given the wrong version of the game?

The DS Lite has L & R buttons.

As Wormetti says, the DS Lite has the L and R buttons. Hold down R and use the D-pad to pan around the screen.
