I produced this disk image by deprotecting my purchased copy of Genesis using
methods described in issue 53 of Computist magazine and issue 13 of Hardcore
Computist magazine. Thus this is a 'clean' crack without any alterations to the
original game. However, a side-effect of the deprotection is that while an
original Genesis disk will supposedly not run on an Apple with a 65C02
processor, this deprotected version will.

From the manual: "The game is set for joystick control. To play with paddles,
press the P key. To return to joystick control, press the J key."

Note that the scorpion is extremely hard to control with anything other than
real Apple II paddles or joysticks. In an emulator, it is often easier to
control the scorpion by having the keyboard 'pretend' to be a joystick than by
using an actual gamepad or other modern controller - and even then, it's still
difficult.
