 If you start with only 5 lives and must go through 11 levels
 of harsh battle, I don't think you'll make it, unless you are
 lucky and fast enough to get extra lives.  But you can save
 your game, and use a hex editor with the save game to change
 the byte at offset 5(hex) to 05. This will return you to 5
 lives.
 I tried fixing it with FF, but I found out that it doesn't
 work - I lose as if I had no lives left. You can attempt to
 screw around with other bytes and hopefully get more lives
 than five.
