[comp.sys.amiga] Hardware & games

I recently bought a copy of the game MENACE by psygnosis.  For a
shoot em up type game I like it a lot.  I have a question for other
people who have it though...Will your copy run on another amiga ?? 
I took my copy over to a friends house (he has a B2000) and it
didn't run.  I thought it was a quirk, but that was all.  Then last
night I took my copy to the Amiga users group meeting, and it
didn't run on an identical A1000 system !!  I was almost surprised
to see it run on mine again !  Is this part of there copy
protection ?  If it is, I'm very paranoid, as I ran my copy for the
first time on a friends A1000 !!  He lives by the mall, so I picked
it up and scooted over to his house..  Serous bummer if it would
only run on his computer !! I think if it is part of the copy
protection, it saves the serial number or whatever when it saves
the high score.
Next, I am very interested in adding more ram to my A1000.  I am
good with hardware projects.  Would someone out there who has the
plans to piggyback more ram chips in the 1000, send me a xerox of
the plans ?  I will gladly let you know how it comes out if you
are thinking about it, but wanna know someone who tried it first
hand first..
Also, one of my friends with a 1000 has a strange problem.  It
seems some colors don't show up on his system.  He gets his R G and
B but some of the 'shades' are missing.  He thinks he has an old
1000 without the halfbright chip or something..Is this fixable ? 
Is it just a matter of replacing an IC or is it more extensive then
that ?
Here is a Q&D hardware  hack for those of you with Quickshot II
joysticks..By changing the value of a capacitor in the joystick,
you can speed up the autofire rate.  Also while your in there, you
may want to run a separate pair of wires down for each of the fire
buttons, and connect one of them across the autofire switch.  Then
you have one button for rapid fire, and the other for manual.  The
cap you want to change for real rapid fire is the .01 MFD (labeled
103) cap.  It is most likely a small green thing that looks like
a chicklet.  If you replace that with a .0015 the sucker will fire
super fast !!  By the way, the only other cap in the joystick is
a 10 MF electrolytic so you wont have any problems finding the one
to change !
And lastly, I have converted 3 atari track balls into amiga mice
ala the article in amazing computing.  Very nice when done, and it
will only take you round an hour to do.  Be sure and get a
trackball with the little  mouse/joystick switch on the bottom..
Happy Hacking !!

	Sounds like his denise chip has a real problem.  If it bothers him,
he can replace it (ask a dealer or repair center for cost) and probably end
up with a new half-bright denise in the process.  It's not too critical if
he doesn't do lots of graphics work.

	My son bought MENACE with part of his Christmas money this year, we enjoy
it quite a bit.  I have an A500 and it runs o.k.  Today I took my A500 to work
and another person had his A2000 there to play Falcon direct connect (which is
great by the way).  Anyway, we tried to run MENACE on his A2000 and it wouldn't
run on there.  It came up and got to the point to press F1 or F2 and just
hung.  I took it back on my A500 and it booted right up and ran o.k.
	The strange thing is that I've never un-write protected the disk.  I am a
bit paranoid about leaving a copy protected disk open for writing.  Maybe the
game doesn't work well on A2000 systems or something.  Any ideas?
