So the high-score problem shows up in emulation?
If so, then I'll need some more information, and perhaps a copy of the image that you were using, if it's not the .po that I uploaded.
> but i'm assuming that's because I don't have a joystick connected to the game port. (both joystick buttons seem to be permanently on
For the II+, a joystick is required.
For the IIe, the Open- and Closed-Apple function as expected for the flippers. The game doesn't require a joystick in that case.

It just kind of messes up the names and scores of the first couple entries (commas and numbers instead of blanks).
Seems to only show the behavior under Virtual ][ with a Thunderclock in slot 7. If it's removed it runs fine.
It runs fine under AppleWin (no slot clock).

Right. The Thunderclock is responsible for the corruption, but it's not a bug.
ProDOS queries the Thunderclock state using the same buffer as what holds the high scores. It's the same issue that my ProDOS Karateka had previously.
I don't know how to avoid it in this case.

Is it possible to save $200-$212 to the stack before making ProDOS calls & restore $200-$212 after?

You could maybe also move the scores up to $280. looks like there are 4 different routines to update the high score list at $200...
$A656 etc - lda 200,y - push lower scores down
$A695 etc - sta $200,y - clear new high score area for name entry
$A79B etc - sta $200,x - store new name/score
$A8B5 etc - sta $200,x - ?????
not sure the routine where it's saving and loading "DAVIDS.MAGIC.2" though which would need to be changed to $280 also, and shortened to 128 bytes.
or disconnect the clock by patching the global JMP like Mike Mahon suggested? (I didn't look at how Karateka got fixed)

If the clock time is irrelevant to the game, just nuke the global page
clock vector, right?

It seems happy for me to disable the clock.
That will be the standard thing for my ports now, if a game uses $2xx and real ProDOS (as opposed to ProRWTS).

The next thing that I should be checking is for games accessing $C020.
Apparently, on the IIc+, this causes unpleasant side-effects like program crashes or machine hangs.
So far, Castle Wolfenstein, Choplifter, and Snake Byte, have been confirmed to do that. I have patched the first two and uploaded to Asimov. The third requires more thought because the routine that does the access switches between $C020 and $C030, so I can't just NOP it or the game will become silent.

I seem to recall a few games which asked if you wanted sound output to the speaker or the cassette port. I suppose if you were using a reel-to-reel tape deck as your storage medium you could have hit 'tape monitor' and piped the sound through your component stereo system. The unpatched Choplifter seems to mirror the sound to both outputs.
Hadn't thought of it before, but I guess you could do stereo audio output on older machines that have a cassette port since there are two outputs. Would require some cabling though.

I used #$30 so that the demo also makes regular sounds. I like it better that way.
Snake Byte played through the cassette output during demo, so it seemed silent without a speaker attached.
Castle Wolfenstein read from the port as a random seed.
Yes, Choplifter mirrored the sound to both outputs.

D-Generation - the prototype version of the famous game on PC - is in Asimov /incoming!
Fully playable despite being preliminary. The end sequence is missing, and there are some bugs in the game, but load/save-game is fixed so you can complete it eventually.

Wow great! I've been looking forward to seeing D-Generation for a while now. Too bad about the missing ending though. I wonder if someone could hack it in? What happens if you teach the end now? Does it just crash?

I mean that no end sequence was included in that version.
I suppose that the final version has one, but we have never seen that version anywhere. Someone at The Software Toolworks or Mindscape might still have it, but I don't know.

So what happens when you get to the end? Does it just hang at a black screen?
Dumb question: Where is the incoming folder so I can snag this? I went to the Asimov archive but I don't see the incoming folder.

You can not download from the incoming directory, you have to wait for the unknown sys-op to move it to unsorted or to its final destination /images/games/collections/san_inc_prodos/

Meanwhile,

The end is just a level that literally says "end" on the floor.
You can run around there but do nothing else.

That's actually kind of funny, reminds me of some really early games that never had proper endings. Hopefully the finished version will turn up some day. Until then I can always view the end sequence for a different version online.

I know this thread is about ProDos ports, but will the original disk images for D/Generation be released? I don't have a hard drive hooked up to my IIe anymore to try the .PO file you posted.

Asimov has .nibs of the original game, however they are copy-protected via RW18 format. Fortunately, since that's the only protection, it's possible to copy the nibs onto real disks.
However, the original game contains fatal bugs like saving doesn't work. I fixed the bugs in my release, but I won't be altering the originals.
I have no plans to crack the .nibs into a floppy version.
CFFA or Microdrive is the future!

Blister Balls 4kb file and Mad Bomber 3kb file (and fixed crashing bug in the original) are in Asimov /incoming.
Enjoy Rodney McAuley's works before Wavy Navy. He re-used the explosion animations from Blister Ball.

If the "serpentine.hi" is not locked then it will save high scores...
like the original did, and which option the pirates removed.

Yes, it's the same David from David's Midnight Magic (which you can see in my ProDOS port because the full graphics screen is shown, instead of the mixed mode which cut off his name).
A fine programmer indeed.

OMG WTF ROFL. I missed a delayed protection.
There's a JSR to $BFF3, which triggers after some rounds of the demo.
I didn't put anything there, so it faults.
Thanks, I will fix that.

Montezuma's Revenge for ProDOS seems to be incompatible with the real-time-clock.
When I install no-slot clock driver and the game won't work.
