Hack description

For anyone who has played this 8-bit masterpiece, you may notice that you can jump infinitely, which removes all challenge from the game.

This looks like a glitch, but actually it's the debug mode which is enabled if, on startup, the game reads a value of 0 (zero) at address 0100 in RAM. It needs to be a non-zero value to start normally, without the debug mode.

A few emulators correct this, but not all of them. Also NES flashcarts seem hit or miss depending on the firmware. Chances are you're going to have a problem, so either of these two patches fix it!

Both Cyneprepou4uk (RHDN) and Dwedit (NesDev) kindly gave permission to upload patches based on their hacking. They each work differently, but produce the same result.

More info in the readme.
