POWERBALL - Enables debug keys. This also requires that you hold down
the left and right shift keys during the JAM Logo intro.
Don't hold them down until the white letters start to appear.
Once the PC-13 screen is loaded, you can let go. You will hear
a "ching" sound during the intro when debug mode has been
successfully enabled. The "ching" sound will only happen if
you have a sound card. If you have a PC speaker, you won't hear this
