hi , i have explored the menus and can't find any way to access classic mode? can you please say how to do that? Thanks!

On The Secret of Monkey Island SE press F10 anytime and you'll switch to classic mode and back again; on Monkey Island 2 SE press F1 for the same results (alternatively, you can press Page Down for classic mode and Page Up for the new graphics).

Thank you so much! This is exactly the answer I needed!! I want to play the game as it was originally as I never did when it came out.

I had the luck to play it in early 1990's on Amiga 500 ("When was this pirate hanged?" DRM), And i can tell that now with new graphics it is still as much fun as it was then with old one (same as MI2SE).
