Trolls AGA

[amilo3438]

Well, you deserve now a big thank you for the hard work, because it was shown, no matter how difficult, each task could be done quickly and efficiently. (something that the younger generation do not understand, right)

The winuaechangelog.txt says following:

Final 2.3.0

Beta 14:

- added 68020 CE-mode very approximate 2-stage CPU prefetch pipeline emulation (not that 68020
don't really have 2-stage prefetch but it still will be more compatible without major changes)
Fixes ATR and (partially) Last Ninja 3 CD32 graphics glitches, (missing blitter waits..)
also more compatible with self-modifying code

Btw. a real 68020 has 3-stage CPU prefetch pipeline, right!? (not sure is that changed in newer winuae versions)

EDIT: JFI, found it; the 68020 3-stage CPU prefetch pipeline was introduced in:

2.3.1 Beta 1
- 3-stage 68020 cycle-exact prefetch pipeline (not much difference compared to old one)

Where can be found old winuae2300_b13 and winuae2300_b14 to test?

old links does not work:
http://eab.abime.net/showpost.php?p=...&postcount=167
http://eab.abime.net/showpost.php?p=...&postcount=173

I suspect that the problem arises from b14, so it should be checked.

EDIT2: Or maybe from b13 (so it also should be checked)

2.3.0 Beta 13
- addaq.x #x,Ax and subaq.x #x,Ax had too long cycle count (this was really stupid bug)

And it seem that are all changes regarding CPU if found in 2.3.0 betas winuaechangelog.txt!

(EDIT: assuming there is no bugs in real unexpanded A1200, this needs testing later)

Yeah, possibly some of the cracks include fix for faster CPUs... but weird, why it then also happens with ipf file (as Sandro mentioned)!?

(Instead of emulation CPU speed, I still suspect in CPU prefetch pipeline emulation problem from winuae2300_b14.)


EDIT3: New findings!!! (final)

Trolls (1993)(Flair)(AGA)(Disk 1 of 2) (CRC32 = 16E8627A)
Trolls (1993)(Flair)(AGA)[cr PDX](Disk 1 of 2)[a] (CRC32 = 79C82C0E)

WinUAE 2.1.0 (2010.04.28) = OK
WinUAE 2.2.0 (2010.06.28) = OK
WinUAE 2.3.0 (2010.09.24) = OK ... (and OK in new WinUAE versions too!)

------------------------------------------------------------------------------

Trolls (1993)(Flair)(AGA)[cr PDX](Disk 1 of 2) (CRC32 = 7AA6830C)
Trolls (1993)(Flair)(AGA)[cr PDX](Disk 1 of 2)[t +3 ATX] (CRC32 = 2DCB1D44)

WinUAE 2.1.0 (2010.04.28) = OK
WinUAE 2.2.0 (2010.06.28) = OK
WinUAE 2.3.0 (2010.09.24) = it start to glitch!!! ... (and glitches in new WinUAE versions too!) ... reportedly, it does not happen on an real A1200 basic (unexpanded)!

... and it also glitches with ipf file (weird)!? (according to Sandro)


EDIT4: Can someone check does the IPF of Trolls AGA glitches in WinUAE quickstart A3000 + cycle-exact enabled? (or behaves same = GFx glitches)
(reportedly, it working on 030 -> http://eab.abime.net/showpost.php?p=904934&postcount=7)

Trolls (1993)(Flair)(AGA)(Disk 1 of 2) (CRC32 = 16E8627A)
Trolls (1993)(Flair)(AGA)[cr PDX](Disk 1 of 2)[a] (CRC32 = 79C82C0E)

above two files tested to work w/out Gfx glitches on WinUAE quickstart A3000 + cycle-exact enabled!

maybe the crack include a fix and disable cpu caches on boot
I sense if you use such crack the game run slower than using the others

do you have a way to check if some game runs with cache disabled?

But now admitted a mistake which should be appreciated. (because it was able to defeat his own ego)

Congratulations!

nothing related to ego....I was partially wrong
anyways you was wrong as well because you said my versions were corrupted, and that's not true

Click "?" button near other WinUAE floppy related GUI buttons. Even easier than using archivers.

Enter debugger (shift+f12), type r<return>. Instruction cache is enabled if CACR bit 0 is non-zero (=last digit is non-zero and odd, usually 1)

Obviously his ego still does not allow to admit that he was wrong (but only partially), because it is not so, he would say the following: "I'm sorry, I was wrong, I blamed you faked pictures without being it first checked and even declared that you are a troll."

(his ego is found a little wounded because someone had dared to enter in "his territory" and thus reacted)

P.s.
his ego is aware that it is not right, and is looking for excuses to equalize the guilt so that nobody is right.

thanks master for the info
I checked this file ,the crack disables cpu caches

Trolls (1993)(Flair)(AGA)(Disk 1 of 2)

btw,
all the other cracks runs caches enabled, that's because there are gfx bugs in winuae
I think Trolls AGA was the 1st AGA game was not tested on the 040/060 by developers
I haven't a real amiga with a 040, but I'm sure the game not works fine on those cpus if caches are enabled

in my A1200 + 020/28mhz runs perfect, there is no need to disable caches
