Can anyone do this for me? I tried to on my own but no matter what I do, it never does what I want it to. Using Stella I discovered that the death routine happens at D1C8 at bank0 and has something to do with $E0, but I can't figure out how to STOP it from going back to the beginning whenever I touch an enemy. I tried putting an NOP anywhere that $E0 occurs right before the death routine, but it doesn't help any.

I gained invincibility by avoiding all the enemies! :lol:

All joking aside, it would be nice to have a trained Pitfall II.
Actually, this past summer I finally played through with a perfect score.

You're probably better off disabling collisions and simply have the character walk through the enemies. Have a look at the Shift-Alt-ZXCVBN key combos. Or to turn them all off, press Shift-Alt-period. And to turn them all on press Shift-Alt-/. Make sure you turn them on before picking up a piece of gold :)
