[BUG] Any game crash enabling interpolation on ZSNESW 1.42

BaD.BoY · Post by **BaD.BoY** » Sun Oct 31, 2004 4:54 am

If you to load the Super Metroid or any game, activating interpolation sound during the game, its ZSNES 1.42 go crash, however if you to activate the interpolation before loading the game, the interpolation go to function normally. In the ZSNES 1.36 this normal functional process and not crash.

I might try.

Edit - Well, seems like it happens. I tried it on several games and it occured.

i did try, it is true

Yeah, I can confirm this too(in fact, I mentioned it in the Official Bug Topic). For me at least, it happens if
1.Music is playing in-game
2.Sound is enabled.
3.No form of interpolation is enabled.
Then, when you enable any form of interplation, it crashes.

The Same Bug happens every time I try to enable/disable
a sound Interpolation.
It seem to happen on any game that is loaded.

I haved this problem for a long time going back,
I cannot remember how far back this problem goes
in the WIP Chain.

I tried: 7th Saga, yess it is a good dump

,
as is all the roms I have.

Here is the Data:

Code: Select all

---------------------Internal ROM Info----------------------

Those Because I still don't understand Exactly what
it does I have just left it off all the time, that goes for the
Video Interpolation too.

Don't tell me, the development team hasn't fixed this bug in the 1.4 release, that's soon to come out.

What File does the Sound Interpolation Source reside in?

Because it is in C, maybe I will take a look(),

I had classes three classes up to Data Structures in C, those I have not
touched a piece of Source code in about 2-2.5 years.

Fall of 2002.

I did keep all of my books those, plus I have about a dozen other books
in ever from Java, Java Script, C, C++, VisualBasic6+.Net, plus a few others.
Mostly Siting in a closet in the basement collecting dust.
My only real problem is lack of my OWN machine w/ SPEED,
and the Compiler&Etc, Software.
I will Admit I don't know a Damn thing about Asembler.
I know Rambling on here, sorry for geting some what off topic,

I am done for know.

It's probably written in Assembler.

Is there anyway to force the Win Zsnes to Debug?
I think this question might have been already been asked.

So we can find this BUG and SQUASH IT.

The debugger only exists in the DOS port of zsnes, AFAIK....but please do prove me wrong.

No, you seem to be Completely correct about the debugger.
I tried to load the Win Version from a Dos-Prompt from within
Windows w/ the "-d" appended to the end for the debugger.
It loads just like normal, No debugger those.
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
I tried to Debug the Hard way, by trial and error(errors are good).
This is the results of testing.

-------------------------------------------------------------------------------
Please note I am using the 10-24-04 release

I used "7th-Saga" as the Test Rom.

I tested all 3 interpolations.

Code: Select all

1=crashed, 0=NoCrash:
CrashStat -- 
1                -- Gaussian
1                -- Cublic Spline
1                -- 8-Point

Disable SPC Emulation had no effect on the Bug.

The bug was NOT present when the Sound was disabled from the GUI.
Using the Sound Enable/Disable Switch.

When First sound Starts, and then I try to Enable a Sound Interpolation Switch,
Bug occurs, and causes a total Crash & Exit.

Low Pass Filters Fine, it seems that they are un effected while sound is playing.

Sound Sampling Rates
Sound is Enabled for these Tests, and is playing.

Code: Select all

Sampling Rates:
0=NoSound&NoCrash, 1=Sound&Crashes, 2=NoAudableSound&Crashes
CrashStats --
1                 -- 8Khz
1                 -- 11Khz
1                 -- 16Khz
1                 -- 22Khz
1                 -- 32Khz
1                 -- 44Khz
1                 -- 48Khz

While I tryed to Enable any of the Interpolation switches,
At any of the Sampling Rates,
and while sound was Both Enabled and playing.
It stilled crashed.
My Conslusion of this test is that the Sampling Rate does not appear to be effecting the bug at all.

I tried to look through the Source for the a point that might be the choke point.

Maybe an Interupt error in the "SPC700.ASM" file.
It could be that the GUI crashes when the Interpolation tries to Interupt the Current playing music to enable any of the Interpolation types, and
Fails to do so because of the bug.

However, maybe it succeded in activating the interpolation,
but when it tried to resume the SPC emulation of the Music,
failed at this point, A memory or Pointer error????
This ofcourse is a Theoretical guess, under the understanding that
SPC700 is the Sound Engine of the Emu.
I thought it might have even been an error in the GUI.asm code,
Please remembe I do not Know any Asembler, So I am fishing for a
Needle in a Hay-Stack.
Correct me where I am Wrong, please.

Here are a list of places there is some thing in these places that
might help with this BUG SQUASHING.

GUI.asm
lines::--> 2,550 -to- 2,570. some things relating to sound cfg??
I choose the above files because I guessed they might be the best location to look.
Hey, I at least tried to look, through that asembler PSYCHO HELL,
nightmare.

OK, I tried I hope the Info I provided will help the Development team.

Nice bug report, joe_devore!

.
Just a little nit-picky suggestion though - did you try restarting Zsnes after disabling SPC emulation? In my experience, at least, changes to the "Disable SPC Emulation" checkbox don't take effect until you restart the emulator. That is, if I check the box in the middle of a game without restarting, there will still be sound output, which would certainly mean the SPC is still being emulated . Checking the box then restaring the emulator does get rid of sound output and fixes the bug for me, at least.

Well, no.
I didn't reset the game after Disabling the SPC Emu,
but the point here is to find the bug, FIX it so we can play roms,
WITH sound.
I just tried it, NoSound, NoBug, w/ SPC Disabled, and SoundEnabled.
This ofcourse still defeats the purpose of fixing the bug.

It would be just unthinkable to play a old favorite or a new one never
tried before w/o sound.
Audio/Music is a KEY factor in Games.

Has anyone High up read this Post yet (Developers, Etc)?

I say, With a FULL, development studios Installed and all neccesary
files&Source on hand, A TEST rom like Final Fantasy's or Chrono Trigger,
Etc.
Compile and Active Debug this Program when it is running, Like I did in
"Data Structures", but ofcourse that was done completely in "C".
Would be nice, but I would need a Whole lot-o-Ram and a Speed CPU,
to do it with, all of which I do not have.

Hi, I don't know if this will be helpful, but I used Inspector IIXII to log crash data.

http://home.ripway.com/2005-1/235510/cr ... 001503.zip

This is log when activated interpolation.

Agozer is correct. The debugger is only in the dos port.
