How do i activate all the hacks?

Do you see:
"Brought to you by MPGH"

In the lower left corner?

im having the same problem, only the no spread is enabled. how do i enable the other ones?

Use your arrow keys to activate them, once you've opened up the menu.

how do you get the hacks?

i figured it out

push 'delete' to enter the hacks menu
use the up and down arrow keys to select the hack
use the right and left arrow keys to enable or disable the hack
