these all work on STEEM

Fuzion CD 2
menu is not correct

confirmed here too.

Fuzion cd 12
Super Sprint
music and sfx play to fast

works fine for me ; are you sure you didn't put Hatari in fast mode by mistake (alt+x)

Fuzion cd 28
Exterminator
during the game the colours are wrong

Are you refering to the first line below the score part on the top, that flickers more or less ?
I see the same on steem, and looking at the code it's quite possible the problem is on real ST too.
Do you have screenshots of the difference between Hatari and Steem ?

No time to look at the others for now, but it may be some FDC problems related to the original removed protection.

nope its not in fast mode (i didn't even know about fast mode till you said something)
on the track selection and the next screen waiting for others to join the music goes so fast (it stops playing on both screen when the counter gets to 3-4)
In STEEM the music plays till the counter gets to 0
and not just the Fuzion cd version it is all versions of Super Sprint

here are some from Hatari
even just let it run through the demo and it starts to mess up
and not just the Fuzion cd version it is all versions

Fusion CD 2 was just fixed by Thomas in the devel version.

Regarding exterminator, it looks like the palette is not correctly changed 3 times per VBL as it should.
What is the value of nSpec512Threshold in hatari.cfg ?
Are you sure you're not running with only 256 colors ? Do you see similar problems in demos using "plasma" effects for example ?

I think this problem could be related to the Timer D...
nash, could you please try to disable the "Patch Timer-D" option in the "System" dialog before you insert that disk into the emulator and reset?

[nash67]

after i disable the "Patch Timer-D" option the colours are correct now
it still has the first line below the score part on the top, that flickers more or less on every screen

[thothy]

Fuzion cd 12
Super Sprint
music and sfx play to fast

Seems like the game reads the Timer-D counter without initializing the timer first.
Disable the "Patch Timer-D" option in the "System" dialog before you boot the disk, and it should work right again.

Fuzion cd 34
Edd The Duck
bombs out straight away

Works for me (with current development version). Which TOS version did you use?

[nash67]

TOS 1.02

[nash67]

okk Edd the Duck works now
?????? one of those mysteries

[thothy]

Fuzion cd 55
The Killing Game Show
freezes up om the title screen

Ok, that game did not work with Hatari 1.1.0, but does work with current development version!

[thothy]

Is "The Killing Game Show" still not working for you? It works fine for me with 1.3.0 !

[nash67]

nope still not working
It doesn't detect the fire button so it just goes through the intro bits (like the picture of the island and the skull as the moon) and after that the title screen the says "The Killing Game Show " cames up and it is stuck on it

and i haven't retested the other fuzion cd's yet with problems on 1.3.0

ok just found something out
If i press my right mouse button the game will start and then the game will detect my fire button (mapped to key z)
In Pompey Pirates 78 you can just press the fire button and the game will start

these all work on STEEM

Fuzion cd 32
Take Two
comes up with the error message " only low resolution" even though it is in low resolution
(it will work if you change to med resolution then back to low resolution)

Well, I spent some time on this one, and it turns out that even on a real ST, it doesn't work.
The menu doesn't correctly restore the TOS resolution as it copies directly the content of $ff8260 without masking it with "and #3", which will confuse the TOS (this a bug in Fuzion menu, not in the game itself)

On a real ST, it will work from time to time and the only solution is to switch med/low res in TOS.

The fact that it works under Steem is because Steem doesn't correctly emulate the fact that unused bits in $ff8260 are not necessarily set to 0.

So, nothing that could be improved here, buggy code on a ST remains buggy code under Hatari

You could add a CRC/hash check to disk image loading and a patch mechanism?

Yes, but what's the point ? I mean, I don't want to patch games that were not properly packed/cracked on the original ST. In that case, people who want a working version of Take Two should certainly use another compilation than Fusion CD 32, but it's not really related to Hatari itself.

Steem has a patch system, but it's mainly to correct situations that steem doesn't emulate correctly (even if it could be used to correct the game/demo in case it's buggy).
Hatari's goal is really to emulate as close as possible the original hardware, it would be a different project to publish some patches for some old broken compilation/games (this is more a job for group like d-bug, who try to repack old games to make them work on more recent Atari configurations).

[TheUMan]

Hatari the only emulator that also emulate bugs ...

Just a joke, but I agree with you; if it doesn't work on real ST, you can't make it work in Hatari.

Smeels like TOSEC to me - disk images are NOT ROMs and therefor CRCs are absolutely pointless.
Just exchange the bootsector for a nicer one - or save your highscores - and the CRC will be changed.
