Looking back through old levels, I found one named Gyrocopter Theme Park, where the point of the level was to fly around with a gyrocopter that, once activated, would last forever. There was a code I found that you could put into the F10 console where you could decide how long gyrocopters in the level would last for. Because it had to be put in every time and that was a while ago, any ideas what the code was?
