FIX FOR BRUCE LEE BY DATASOFT, The Paperboy (FOR DISK VERSION ONLY)
First, Bruce Lee is an excellent product. It's just that (aaarrrggghhh)
you have no `falls' left, and you feel yourself quite near the finish of the
game. Suddenly, one of those little dots floating on floor taps your foot and
you get zapped. You see the sign "Game Over" and you feel pretty pissed, and
wish you could open the drive and rip the disk to shreds - but wouldn't that be
a waste? So, fix it! One thing you could do is play option C, one player vs.
your opponent played by the other player. But this time, play alone, and make
sure the second joystick is calibrated wrong. If the computer sees that the
Green Yamo isn't moving, it will take over, so a wrong calibration will make it
move all of the time. So, you're playing, but that stupid ninja is in your way
and it won't let you win. Alternative? Eliminate him. And this is how you do
it. Get a disk utility, preferably Norton Utilities. Zap the Bruce Lee disk,
with the following information.
Sector 271 Sector 271
Offset 139 and Offset 354
Change 09(hex) to 63(hex) Change 09(hex) to 63(hex)
That's all there is to it. Now you play, the Green Yamo flying around
crazily, and the ninja... hmm... the ninja seems to appear for a quick second
then disappear. That's what's supposed to happen and there's your fix. Bye!
