There were some very elaborate copy-protection schemes. Like, “go to page 12 in the manual and enter the word at the bottom of the page”.

So you had to take the code the game gave you, turn the wheel to the correct spot, and then enter the result the wheel gave you.

One of the most famous moments of Metal Gear Solid is an anti-piracy measure.
Split the wheel and copied it on the school copier. ;) much easier the copying the whole manual that was sometimes needed
