Haven't tested this personally:

Arkanoid v?.? (to run on most Mac's)
-------------------------------------
? patch the game to make it Mac OS 7 friendly
- Note: some reports from PowerBook owners say that even
after patching, Arkanoid still crashes on their machine
(odd screen size, maybe?)
- switch to B/W (1-bit video) before playing
- CODE 4, offset 0042
- change 66
to 6D

# Enable "super-player" mode (free capsules on demand)
- start the game as per normal
- pause the game
- type: dsimagic
- resume game
- catch the special "DS" capsule coming down
- press a key to get a power
- A = sound toggle
- B = Boss screen
- C = catch
- D = extra balls
- F = go to last round (level 33)
- L = laser
- P = player (extra life)
- S = slow
- W = break to next level
- X = let computer play
- 0 = pause
- 9 = resume

Edit: Replaced 'xxx 7' with 'Mac OS 7' - IIGS User

I wonder if the version on this site is already patched that way. Many old game uploads are already patched either for copy protection or compatibility.

"Does Arkanoid run on Mac II series computers?"

Well, you're in luck (sort of.) I worked for Discovery Software last summer,
and (thankfully) left before all this nasty bankruptcy business came about.
It was a very small company, and I got to do a lot of different jobs -- one
of those jobs was customer support for Arkanoid.

There are three types of compatiblity problems with Arkanoid:

1. Not enough memory. This occurs with Mac 512ke owners; the program needs
about 10k more than is available for use. Solutions: Try booting from
an ABSOLUTE bare-bones SYSTEM. That means only one (small) DA, no fonts,
INITs, whatever. This may work. Other solution: upgrade to 1MB ram.

2. '030 problems. Version 1.00 of the program has nasty problems when trying
to run on any '030-based system. These problems were solved in version
1.10, which was released in August 1989 [quietly - no packaging changes
were made, and no dealers were notified.] The new version was tested and
is happy running on a //x, SE/30, and presumably will run on the //cx
and //ci as well. Added attraction: the new version allows the option of
neutral-grey background (instead of those annoying B&W patterns!) - this
is the easiest way to tell the two versions apart.

3. Multifinder problems. Arkanoid is very multifinder-friendly, BUT due to
its use of alternate screen and sound buffers, it will NOT run under
multifinder on the Mac SE or Mac Plus. It will run under MF just fine if
you are using a Mac // or later. Other games, such as Dark Castle, also
have this limitation.

So, how can you get a copy of Arkanoid 1.10, you ask? Good question. The
company is in a lot of legal hot water right now, which I am not familliar
with, and I can't tell you what will happen. My best guess is that another
company will eventually buy the rights to ARKANOID, which is still a popular
product, and market it. In the meantime, call mail-order houses which still
carry Arkanoid inventory, and ask them to send you one of the NEWEST copies
they received. Definitely get a money-back promise so you can return it, if
it turns out to be the old version... Realistically, your chances of getting
a copy are slim indeed- there are probably only about 1,000 copies of Ark1.1
extant. If you call places that use INGRAM MICRO-D as their software
distributor, you have a chance of getting newer copies.

I'm not sure what the legality is of distributing software whose copyright is
owned by a bankrupt company, but I will not get myself in trouble by testing
the idea! Perhaps I can do a file-compare of version 1.0 and 1.1, note the
important changes, and post a patch-file. Don't hold your breath; I've got
exams coming up very shortly. Maybe in a week or two...
