We have updated Leisure Suit Larry 2 for both PC and Mac. Please check your accounts for the patch that will add Leisure Suit Larry 1.002.000 (PC) and the updated Mac installer.
This version of Leisure Suit Larry 2 has the working phone number (555-0724) that allows you to enable cheat mode and other hidden features :)
Thanks and have a nice day :)
A little note about doing said phone number - it bypasses the intro to the game completely.
