THE APllcation does not crash  when soundmode is 0 

 

it only cashes every second time once i  have set sound mode to 1

 

the first time I set it even the dmd doesnt work..  which im using ;

 

controllerMame.get_updateDmdPixels(DMDArrayChangeUpdatesHandle.AddrOfPinnedObject(), DMDController.instance.width, DMDController.instance.height);

the funny thing is  the compiled lib isnot using the 64 dll but the crash report says the violation happens in there??

 

(i use the 32 ll because unity editor only supports 32 and I wan to test using the editor ) prerviouly i had to build and test outside the editor . that doesnt even work anymore.. I tried to test building a dll using your 64 dll and unty threw a huff over it  even when disabling the editor as a target.. it could not find the namespace of the dll i made using the 64.   

[tictox]

mmm. if i diable all dmd code it works fine without crashing the app .. still using the old Game.Settings method. You method does not still does not work same problem , object reference error .. now to find out what is happening with this dmd..

[tictox]

narrowed it down to "get_updateDmdPixels" crashing the app. I use gc hanldes and uses alloc to pin an address for the pixels I tested this handle as well via "IsAllocated" and it is fine but as sonn as i call :

controllerMame.get_updateDmdPixels(DMDArrayChangeUpdatesHandle.AddrOfPinnedObject(), DMDController.instance.width, DMDController.instance.height); ...... it crashes

 

Also when this is commented out  sound mose works like a treat(old method) also not crashing

 

getting closer but now im in no mans land

confirmed and tested "get_updateDmdPixels" is causing the app to crash when sound_mode is 1. If sound_mode is 0 all is good. I tested it with VPM visible and VPM DMD visible to rule that out as culptrit. It does not matter. If sound-mode is 1 then this causes the app to crash every second time.  i am freeing the handle.

 

calling pause when sound_mode is 1 also does not stop the audio.

 

all works fine when sound_mode is  0 

[toxie]

There is still something weird then, as it should not crash in the 64bit version, if this one should actually not even be called as you say.

Are you sure about all that?? Did you run both setup and setup64 also to install both com objects?

 

About the missing pause: I might be able to add this, but don't bet on it.

[tictox]

i have VP with VPM installed on a other drive, copied both your new dll to thier and installed them yes. I use a ,net exe to build the bridge named tlbImp_32.exe . i have two versions or it the :-_32" and "_64" i added the suffix  to tell them apart and keep them in that same directory. anyway i use this the call tlbimp_32 VPinMAME.dll /out:VPinMameTypeLib.dll on the  cmd line to generate my lib. This lib is copied to the unity plug in directory. the output name is based on the input name so you can not make a mistake, also the unity editor will though  a  huff if i build usng the 64 bit. so base on the out put name , and based on the unity editor i know i am build and using th 32 bit brige dlll named VPinMameTypeLib.dll. i. have to even update my vp vlass to use the call using - "using: VPinMameTypeLib.dll;" or "usingVPinMame64TypeLib.dll" the latter fails anyway because it somehow cant find the namespace.

 

 

Anyway what is weird is that even when  doing all that the error happens in the 64 dll you provided. I CAN NOT even remove that dll from the vp/VPM instll directory. The game wont even start the com object. So nothing in my game except the lib i built is using the com object, the lib was built from the 32 bit dll,. .. but the eorror is in  VPinMAME64.dll regardless. so it is running.. but not from me or my lib.. It must be the com object that loads and runs the 64 dll

Phew.. This also goes over my head.. No clue how all that COM madness interacts with your lib then.. To me this is also pretty much a black box that i just use/program..  :/

[tictox]

thanks toxie, when build the app it does not crash , so this is a unity editor bug.. it only happens in the editor

[toxie]

??? Even more weird..

[tictox]

i once saw a fatal error dialog before a a crash .. which had a quit option to close the editor, but only once. It is complaining about changing the working directory( my game) to that of (one of the alt sound file paths, i think get off the fence) anyway it said this is not allowed. if you change it via code you should change it back.. funny thing is the datapath is read only to us in c# .well i guess i will just using the  old sound in the editor while i  finish the game.. hope unity sort out this error in the editor when using System.Runtime.InteropServices;

It's probably worth noting that there are known issues trying to unload VPM, and we don't really know the cause. 

 

If you make a debug build of VPM you'll find you can't run a table more than once in VPX.   You'll get a debug assertion inside Microsoft's library code on the basic file stream IO functionality.     That suggests something is not unloading completely.   Might be contributing to whatever problem you're having. 

[toxie]

Also true. Multiple people already looked into that one over the years and failed resolving it..  :/

[tictox]

normally i n such  case i nromally rename the route variable and then get a million errors from the compiler. These errors are like your stack trace and it is quickly possible to tack it from it source. 

besides all all that,  Toxie do you know why the alt sound does not pause when you tell VPM to pause. Pause works perfectly when sound is orginal. When setting the sound_mode to two,  the emulation stops, but not the sound.

[toxie]

As said, this is currently missing. And i do not know if this is easy to add, as this feature is playing the sound 'in parallel' without much knowledge about the emulation core itself.

But i'll look into it..

[toxie]

i just added some code, could you please test if the pause now works for your use case??

[tictox]

Thanks for trying I downloaded the zip from the org post and installed both dll's, does not seem to make a difference.. alt sound still plays when i pause the vpm controller

[toxie]

i did not update those dlls yet.. :/

could you compile your own ones please for now/testing?

[toxie]

*ping*

[jwosi]

After updaing to this version, i have a ton of tables that now error out on start with this error: "Game Name Not Found" .GameName = cGameName

[toxie]

I guess you mean the newer Stern SAM tables? Then most likely you used an unofficial build from the 'other forum'?
