After much procrastinating I'm finally getting around to testing all
my Apple IIe games on my IIgs to see which ones work and which ones
don't. I have a fair number of originals and a lot of pirated games,
so there should be a pretty good mix. I plan on testing the ones that
don't work with the built in smatport with an actual Disk II card to
see if that helps things. I'll post the results this weekend.

To help speed my testing along, does anyone have a list of games that
only work with a real Disk II card? I've heard that Karateka and Drol
are two such games, and I did get Drol working by using the card, but
Karateka still wouldn't work (both are non-originals).

From memory, I could never get "Speedway Classic" running on my IIgs -
I never did work out for sure whether the game was incompatibile with
the IIgs or something else that prevented it from running (e.g. dirty
disk, etc). But I'm pretty certain the same disk worked fine in my IIe
when tested.

I'd be quite interested in your results. Presumably you will post your
findings somewhere when they're completed?

Cheers,
Mike

Karateka works well on a smarported IIgs. I've cracked it recently on a
real IIgs with a 5"25 disk drive attached to the smartport interface of
the computer.

The programs that may not work are the ones that rely on false
microprocessor opcodes which exist for the 65c816 and not for the
65c02/6502. Some Sirius games are like that. I've been obliged to NOP
some areas to make them work on the IIgs.

And if you want to go further, list IIgs games that do not work on a ROM 3.

Good luck,
Antoine

I couldn't get Karateka to work on my IIgs Smartport, maybe it's the
crack I have. Is the one you're using available somewhere?

I'm using a ROM 3 IIgs if that matters. If anything it should be MORE
compatible with Apple II software.

To clarify, on occasion, while traveling through Hyperspace, you'd get
get pulled out by ... the Nasties. On the //e, you'd fight it out
with them. On the GS, control was impossible and you'd always get
slaughtered. This was on a ROM 1 Woz Special. At least that's what I
remember from the late '80s.

Testing is going well. I'm about half way through my non-original
(i.e. cracked) games with about an 90% success rate. I'll make a big
list of what worked and what didn't (and how it crashed) this
weekend. Games seem to have one of three problems:

1. They start to boot and crash to a monitor program (* prompt). This
is the most common problem.
2. The game won't boot at all with a Check Startup Device message.
This isn't nearly as common.
3. Game loads but has graphical issues (missing graphics, graphics not
updating, etc.). This is the least common

I'm hoping to test the ones that aren't working with a real disk card
to see if that fixes the problem (ala Drol). Failing that I'll try a
different crack and see if that works. Oddly enough one game that
refused to work on my IIe (Lock n Chase) works just fine on the IIgs.
I assume this is a Duo Disk issue and not a IIgs/IIe issue.


A little off topic, but does anyone have a good working .dsk image of
Lode Runner? I lost my original and the ones I can find either crash
(even on my IIe) or say they're actually a data disk. Championship
Lode Runner worked just fine so I can't see why Lode Runner wouldn't
work.

Also keep in mind that due to the sheer number of games I need to get
through, when I say I tested a game I'm just seeing if it loads up and
I can play the game for a few seconds. I'm not doing in-depth testing
that would find problems that occur in games like Elite or Sky Fox.

Lode Runner, Elite and Skyfox all work on a IIgs computer. Again, see
http://www.brutaldeluxe.fr/crack/
If I were you I would focus on early games, the ones using false
opcodes.

Oh I know Lode Runner works, but I just can't find a good disk image
for it.

I know that Skyfox and Elite load and seem playable on the IIgs, but I
hear they have gameplay issues that aren't obvious right away. Are
you saying the cracks available in that directory fix these issues?

I'm not focusing on any particular time period, I'm simply going
through my library of games.

I think we are not on the same line.

What is your objective? 1/ Are you checking disks that do not load on the IIgs because of the smartport interface (as written in your first post) or 2/ are you checking the behaviour of programs because of either the higher speed or the different microprocessor of the IIgs?

The crack I did and uploaded to bd.fr/crack/ are working unprotected disk images of original games. All those cracks (but Kaves of Karkhan) were done on a ROM 3 IIgs and then tested with success.

My cracks there answer to point 1 but do not guarantee point 2.

I'm trying to do both however due to time it's mostly 1 rather than
2.

My setup is:

* ROM 3 IIGs
* Speed set to normal (IIe speed)
* 5.25 drive connected to the Smartport
* A 5.25 Disk II card (see step 3 below)

My current testing methodology is:

1. Attempt to boot the game
2. If the game boots play the game for a few moments to see if it
appears to work (no funny graphics glitches or other problems)
3. If the game fails to load I try it again with a 5.25 drive
connected to a real Disk II card

I'd like to test the games thoroughly but I just don't have the time
to play through each and every one (I've got hundreds of games to get
through).


> My cracks there answer to point 1 but do not guarantee point 2.

Hopefully your cracks will fix the bulk of the games that aren't
working. So far I've only run into a small handful of games that have
gameplay issues after they load.

* Crystal Castles - Graphics don't appear to be updated. You can see
the gems disappear where Bentley is supposed to be moving, but he
stays stationary. You can hear the rest of the game running as well
(enemies moving and such) but they don't appear on the screen. The
game is actually playing though as I managed to stumble into a warp an
go to screen 3.

* Impossible Mission - There are funny white dots that appear behind
you where you move, like the graphics aren't being updated properly.
The game seems to play alright though.

* Mr. Robot - Same problem as IM but much worse. The game is barely
playable because of the mess of graphics that end up all over the
screen.

* Night Flight - Some of the graphics don't load (only the cockpit).
No idea if the game is still playing or not because I don't know the
game, might be crashed.

OK. Thanks for the clarification.

Question: where is your Disk II controller card installed? In slot 6
and you switch from "Disk port" to "Your card" in the control panel or
is it located in another slot?

If it is in another slot, that may explain why some games do not load
or crash, programmers/crackers assume the Disk II interface *MUST
ALWAYS BE* in slot 6, ahem!

Yes the card is located in slot 6. To use it I attach the drive to
the card, select My Card and then type PR#6 from the command prompt.

U R right, Alex. This is something I have forgotten.

IIRC, there is a protection check when you reach the clouds and either
you are stuck above the clouds or the game reboots, I can't remember.

I need to check that on my crack, I missed the thing, that's for sure!

Just keep the nose of the SkyFox pointed at the sky and increase
altitude. Eventually, the game mode will freeze or not. You can't
properly play the game without getting above the clouds, because you
need to take out ground targets AND enemy fighters to complete missions.

Put a blight on playing it on the IIGS, otherwise excellent game for
the Apple II.

Yes, but there is a minor problem with using Alternate Display Mode:
the control panel sets up an interrupt generator for the IIGS to
interrupt every vertical blanking interval to copy High-Res Page 2
from bank $00 to bank $E0, making the games "stutter". The reason for
this is because the Mega II does not shadow Page 2 text or high-
resolution Apple IIe graphics.

I have a few games that appear to "fail" on the Apple IIGS because the
games use text Page 2 for some reason--often, this is just for showing
some text so as to configure things like how many players and whether
to use joystick or keyboard, but they revert back to Page 1 high-
resolution graphics in order to play the game. I find myself enabling
Alternate Display Mode just for that period of time to read the text
display, but disabling it just to be able to play the game without
having sound generation and timing issues!

IIRC, the bug is actually in the FPI.

The ROM 3 CYA's does actually fix that, but for compatibility reasons with the ROM 00/01, it's not shadowed unless you enable alternate display mode (which does NOT use the VBL interrupt-based copying method on the ROM 3.)

Ok I'm ready to present my findings. I'm happy to report that the
success rate was rather high, and I'm confident that most of the non-
working programs can probably be fixed by finding and using a
different crack (some cracks worked while others failed). There were
only one or two showstoppers for me that would make me hold onto my
IIe, but more on that later.

As I mentioned earlier, My setup is:

* ROM 3 IIGs
* Speed set to normal (IIe speed)
* 5.25 drive connected to the Smartport
* A 5.25 Disk II card (see step 3 below)

My current testing methodology is:

1. Attempt to boot the game
2. If the game boots play the game for a few moments to see if it
appears to work (no funny graphics glitches or other problems)
3. If the game fails to load I try it again with a 5.25 drive
connected to a real Disk II card

4. Enable alternate display mode and see if that fixes anything

I'll list the games by category (works, doesn't work, works with disk
II card, works with problems, etc.) and by whether or not they
original disks or copies. So without further ado, here's the list:

So in the end the only real deal breakers for me were:

Goonies
Mr. Do
Wasteland
Archon
Realm of Impossibility
Rescue Raiders
Mr. Robot

I'd really like to get working versions of these games. The rest I
could live without, but these are some of my favorites (especially
Wasteland!). I'm going to start looking for working cracks of all the
games I listed as not working and post my findings.

I hope this information is helpful to everyone and I hope people will
add to the list.

grab the sounds from the C64 version
graphics of the EGA DOS version
and somehow hack into the Apple II version
and of course, make it all work!

But seriously, I love that game. Haven't played it since the 80's or
90's probably.

Anyone have a clue on the Black is Red issue I saw with a few games?
The emulators don't do this, only the real hardware. It's also not
all the black graphics, only some (like the building tops in
Rampage). It's very odd.

OSome updates:

A.E. - Found a crack that gets past the title screen (with graphics)
but the game reboots and crashes
Arcade Machine - Found working crack (is this game one or two sided?)
Cannonball Blitz - Found a working crack, but the graphics don't
update so the game is unplayable
Rescue Raiders - The crack I had was actually working, but the little
Sir Tech intro doesn't display. The game starts after that but
crashes as soon as the game screen with the helicopter is shown.
Might version 1.3 fix this? I can't find a .dsk file for it.
Robot Rascals - Found working crack

Wasteland - I found a way to get the game working. You need to make
copies using the games built in utility from a real set of disks, then
use the Wasteland Boot disk found in the asimov archive to boot the
game. When the game prompts you to insert your play disks, use the
disks you made earlier. Oddly the play disks in the archive or disks
I made from the boot master wouldn't work, only the ones I made from
the real disks.

Zorro - Found working crack (Zorro alt 3)
Star Blazer - Found working crack
Mr. Do - Found working crack
Spy's Demise - Found working Crack
Shamus - Found working Crack
Impossible Mission - Found a crack that didn't have the graphics issue
Repton - Found a working crack
Moon Patrol - Found working crack
Super Boulder Dash - Found working crack
Russki Duck - Found working crack

Realm of Impossibility - No luck with the crack in the archive, but I
found this note on a webpage that leads me to believe it's possible:

Jack R. Nissel (COMPUTIST #56, page 20):
Realm of Impossibility DOES work on the Ilgs,
it’s EA’s protection routine that does not. See
COMPUTIST #50, page 20 and also
COMPUTIST #49, page 16 for infomtation on
how this is done. A salesman friend has asked
me to crack several EA programs for him
because a customer couldn’t get them to run on
a Hgs. However, the cracked versions run just
fine. Keep in mind: there is a second disk check
at $569 (and $5F8 or $5FE) that should be
looked into. Some of the EA programs need the
JMP $569 to shut the disk drive off at the end
of a disk read, so I edit the calls to $5F8 (or
$5FE)

It crashes at the title screen on my IIgs. Seems to work on my IIe
though.

I've never heard that High-Res Page2 wasn't shadowed. It displays fine
on my ROM 01 GS with Alternate Display Mode OFF. TEXT Page 2 doesn't.
There is even a register ($C035 bit 2) to turn on/off hires2 shadow.

Is it possible that what you are seeing is caused just by the Alternate
Display Mode interrupting for Page 2 text even when it isn't being
displayed?

So after all of this testing I have a few questions for everyone:

1. Why do some games crap out on boot and say "Not a Startup Disk"
with the little sliding apple graphic?
2. Why do some games show a red color where it should be black. Not
all the black graphics, just some parts of the black graphics?
3. Why do some games not show all the graphics? You can hear them
playing, but half of the graphics are missing or not being updated.

Is there a way to fix any of these problems?

Weird things that make me believe your IIgs has issues. Do you boot in

Yes I do, but doesn't my IIe also boot in 80 Column mode? Could that
be causing problems?

I stand corrected. Thanks guys. I'll keep trying new games as I find
them. Only one more to add for now:

Copy of Star Warrior (by Epyx) works just fine.


Now if only we could get some of those non-working ones working
(especially those EA games) or fix that red/black issue. Still, I'm
happy with the percentage of games that do work.

Very interesting. I'll compare your lists to any games I've looked at
for emulation problems in the past.

Hopefully a resident GS expert can have a look at the red/black
issue ... is this some black1/black2 palette issue? You could "visit
the monitor" whilst in the game to test that theory. All my II's are
in storage unfortunately.

Cheers,
Nick.

Yep I checked last night:

80 Columns
Black Border
Black Background

It's not set to default because I find the blue hard on the eyes and
most Apple II games used a black background which looks silly with a
blue border.

Did you try changing it back to the default setting to see if that
made any difference? It might be something that simple that is causing
your problem.

I set everything to the defaults and I'm still getting that odd Red/

column mode tomorrow.

I'm not sure what you mean by not booting a 6502 only.

Ok I did some testing with the 40 column turned on. Amazingly just
about everything works now! Even Beautiful Boot works, which makes
things much easier.

Games That Work With 40-Columns

Originals
-----------
Apple Panic
Archon
Archon II
GI Joe
Kung Fu Master
Goonies
Realm of Impossibility
Strike Fleet
Super Boulder Dash
Track and Field
Wasteland (no need for the funny boot disk)


Copies
======
Aquatron
Archon
Black Magic
Crystal Castles
Eagle Eggs
Flap & Smack
Gumball
Lady Tut
Narnia
Neptune
Night Flight
Pitfall II
Repton
Rescue Raiders
Ruski Duck
Sky Fox
Spy's Demise
Spy Strike Back
Super Zaxxon
Up N Down

AE, Mr. Do (original), Moon Patrol (original), Twerps, Burgertime, and
Cannonball Blitz still don't work. I'm fairly certain that if I play
with some of the alternate cracks that AE and Cannonball Blitz will
work. I'll try that later.

So basically 99.9% of the games work now. I'm really happy with the
results of my testing.

I still find it odd that the IIgs 80 column mode was the cause of all
the problems, but I suppose it's a bit different than having an 80
column card in a IIe. I'm sure there's a long winded technical
explanation that I won't understand anyway. ;)

The red/black bug still bothers me though. 40 column mode didn't fix
that.

Some originals still don't work (Mr. Do, Moon Patrol, Drol, etc.) but
much like the Rom 01/3 compatibility issue, as long as there's a crack
that works I'll be happy. I'll post an updated list only what doesn't
work and keep updating that as I find new things. A list of things
that DO work is too unwieldy to manage. :)

Me neither. But the 8-bit line booted in 40-col mode, so as to do the
IIgs.

Apart from some Electronic Arts programs, which behave as described?

Use my crack of Moon Patrol. It works on the IIgs and you get the
lunar base for the same price. Still and always available at

Hmm, there's a video of "Moon Patrol" bitcopied to HDDD A2:
http://www.bootzero.com/video/4.html

So I guess the original 5.25" disk must've been working, too.

Have you tried with both IIgs' on-board and controller in slot #6?

No I didn't, but I believe I read that the reason it doesn't work is
that it uses an illegal opcode which wouldn't be solved by using a
disk card.

Speaking of games that need a disk card, is there a crack of Drol that
works without the card?

Tiny update. Thanks to Antoine we now have a crack of Drol that works
on the IIgs! So that's another one down.

Burgertime still stumps me. I had this on my IIe back in the day
(the Freeze crack with the joystick) and it worked just fine then, but
now when I try it on either my IIe or IIgs it crashes right after the
crack screen. Any ideas? It's not just the file from Asimov, my copy
that used to work does the same thing!

One on One I could live without. I never thought it was all that
great of a game. I'm sure the crack to get it to work on the IIgs
would be welcomed by some, but it's nothing I'd get excited over.

I had Burgertime as well back then - the same crack - and it would
only run on my dad's II+, never on my Laser 128EX.

But it DID run on my IIe. The exact same IIe I still use! The only
thing that' changed about my IIe setup is that I'm using a DuoDisk
instead of two 5.25" drives. I can't believe that has anything to do
with it.

I hate to necrobump this, but has anyone ever figured out the cause of this? Basically some black pixels show up as red for some reason (look at the Rampage title screen for example and you'll see what I mean).
