Journey sound sample in mame2003-plus, solved

grant2258

Problems is there are so many samples kicking about and being changed you dont know what your going to get would be best to rip from a cd for moonwalker!

So why is it that this journey sample works in 2010 but not 2003plus? It's a mono track? Journey . The only thing I see is that it opens as 32 float in audacity. If I cut the time to 1:50 then export it as wav 16 bit it works in 2003plus but at the cost of not having the whole song.

Are you guys testing a sample that fully fits? Or are you just cutting it to 8 bit to fit? If you have a working version what file size is it?

@Riverstorm you can link your 8 bit version, I'll try it. But this seems like something we need to update like mame2010 did since it works with it. It seems like it needs allotted more memory to fit larger files, journey is probably one of the largest samples mame uses or close to it. So if that works mostly everything else should too.

From what I could tell, the samples are all read into memory then are able to be called at any time. I think that journey sample just over loads the memory and eventually crashes the system.

The sample works fine i tested it on final fight you problems is else where. Do this on retropie in the bios folder make the following directories mame2003-plus/samples/ffight
copy the sepways.wav there and rename it too track02-01.wav

start final fight put the the cheats on and listen it play from start to finish it will start on the first level dont pass this level or you'll get the normal music because you missing the other samples.

@grant2258 interesting, if you take the journey sample from the link and test it in the journey service menu under cassette, do you get the same screech then crash after a few seconds I'm experiencing?

grant2258

well thats the sample tested is working fine

mahoneyt944

@grant2258 hmm well that's a good test anyhow. We must not be setting the parameters up right in our driver.

I saw this in common.h that looked interesting, but I'm just browsing through files. Game sample large caught my eye.

struct GameSamples
{
	int total;	/* total number of samples */
	struct GameSample *sample[1];	/* extendable */
};
 
#define	GAME_SAMPLE_LARGE		10000000 // 10MB

grant2258

thats stuff we added during adding flac support

mahoneyt944

@grant2258
Let's find the difference in cps1.c to our mcr2.c if the sample works there. The first difference I see is the attribute supports stereo. Final fight is using 2 channels.

grant2258

thats not a issue it support 2 mono samples for stereo if you have them both else it plays the one mono sample in both channels. Again this is part of the ost flac support update. Have you debugged it at all to see where its crashing?

mahoneyt944

@grant2258 no, I'm at work so I can't right now. What happens though is when I go to the service menu and enter the cassette test menu. When I flip the up button to start the cassette I hear screeching. If I press down it stops. If I let it play eventually after about 30 seconds it crashes the emulator and throws me to emulationstation. So I took that sample, opened it in audacity cut it to 1:50 (originally 3:03) then exported it as .wav 16 bit pcm. I retest the above senario and the sample works just fine. So next I try the cut sample at 1:55, this time I get the screech and crash. For some reason it doesn't like the sample size over a certain size.

But then you got the sample to work through final fight, so I really don't know. It must be related to how we are initiating the sample with the mcr driver? Maybe the output is wrong, 2010mame looks like this:

static DRIVER_INIT( journey )
{
	mcr_init(machine, 91475, 91464, 90913);
	mcr_sound_init(machine, MCR_SSIO);

	ssio_set_custom_output(4, 0x01, journey_op4_w);
}

And our 2003plus wip

static DRIVER_INIT( journey )
{
	MCR_CONFIGURE_SOUND(MCR_SSIO);
	install_port_write_handler(0, 0x00, 0x00, mcr_control_port_w);
	install_port_write_handler(0, 0x04, 0x04, journey_sample_select_w);

	mcr12_sprite_xoffs = 0;
	mcr12_sprite_xoffs_flip = 0;
}

grant2258

to be honest i just compiled it a while back and got the same result not really looked into it much yet cold be anything need to see where its segfaulting to get a clue else your just guessing. The driver is completely different to the one we are using

mahoneyt944

@grant2258 yeah that's the next step.

skj

Have you tried the sample at Twistys mame samples?

mahoneyt944

@skj I think it's the same sample from what I can tell

comment this for now and change it to if(1) something else must be triggering this will need to follow the code at some point this code.

mahoneyt944

@grant2258 that's what I was looking at earlier but passed it when you said about in being flac related. Does that fix the issue with the sample loading? Can't we just raise the GAME_SAMPLE_LARGE to fit our sample it's capped at 10 mb and our sample is 15+

grant2258

I think i know what the problem is there is a flag that checks if contents is ost sample

https://github.com/libretro/mame2003-plus-libretro/blob/0134c428b75882aa474f78dbbf2c6ecde49b97b7/src/sound/samples.c#L32-L45

will check it later on i would guess this is the issue with using big samples like this.

grant2258

@arcadez2003 do you have links to them samples you had to shrink sorted the problem will test the ole samples that never worked before as well. This is actually great doing it this way because it unloads the sample when it stops if its huge its so smaller systems like the mini collection can play the samples without loading em all at one time.

I still got the one for Teki Paki how to get it to ya though.?? im not sure if we can share samples on here.??

grant2258

think samples are ok to be honest as long as its not the full metallica collection! I could always drive round bring a thumb stick sanitize it throw it you while maintaining a two meter distance just for something to do during this lockdown is driving me nuts!. Seriously thrown me a link anywhere on github if you dont want to post a link here.
