lr-mame2003 driver improvement and backport

dankcushions

i guess samples are not static files like roms. they could be re-recorded at better fidelity, etc. the names of the files should remain the same, though.

@riverstorm Or if you know that you have a perfect samples set for 2003plus you could do a DIR2DAT using CLRMamePro which scans a selected directory and adds CRC's/SHA's (if selected) and spits out the DAT file.

Also, did somebody make a Datfile of just the new and updated roms for 2003plus that are needed so I can add them to my filtered 2003 set ?

My understanding about samples is that mamedev considers them like bezel images or any other assets which can't be validated digitally against the original like can be done with ROMs. The logic being that samples are therefore supported but no one set is 'endorsed' by adding it to the source in the driver.

That being said, I personally think it sounds like a good idea to consider adding recommended sample crcs to mame2003-plus if there is a consensus about what sample sets are good.

Here's the samples from Twisty's I used with mame2003-plus (processed with the DAT so all of them are named and packed in the proper zip). I am using enhanced unofficial samples where possible.

It has complete CRC and SHA1 information. I imported the ROM header information from the main DAT so a missing ROM from a set will show as "Astro Blaster (version 3)" vs. "astrob".

The year/manufacturer is based on the ROM set and not who actually made the sample or what year. Process it like a ROM set (Set and ROMs checked) and not samples. I would build it in a new folder and cross link to your original set until you feel comfortable it's correct before merging.

I am ok with endorsing Twisty's samples but I do use the unofficial enhanced versions of some samples like (dkong, berzerk, invaders, qbert, rallyx, starcas, etc. ) he has listed on the site. I am ok with either though.

I've been thinking about this and I don't think it would be to hard if done in non-merged mode.

My thought is to make a subset of mame2003-plus. This set would be around 1.5GB or so. You would be able to dump it in the ROM directory and play any new games or changed games from mame2003-plus only.

Then if you want dump this subset into your main lr-mame2003 folder it would match exactly the mame2003-plus full set.

One minor issue is lr-mame2003 has these two sets which don't exist in mame2003-plus. So it wouldn't hurt anything except they would be removed if processed with the mame2003-plus DAT. That way instead of like 28GB for the two sets it would be like 16GB or so.

Only exist in lr-mame2003:

Cabal (US set 2) (cabal2)
Urashima Mahjong (urashima)

I would rather wait until those 4 non official ROMs are decided on what to do. It would require processing the set a few times to do this but I don't think it would be to hard.

@markwkidd - Do you know if you can add hash information to the sound sample sections of a DAT?

<sample name="run01.wav"/>
<sample name="run02.wav"/>
<sample name="run03.wav"/>
<sample name="jump.wav"/>
<sample name="dkstomp.wav"/>

@riverstorm I ran the samples dat you posted and noticed that you are using 'Gorf (0.125u2 & Newer)' from Twisty's. Is this compatible with MAME 0.78 ? I looked inside the zip and it seems to contain 11 samples at 0 Bytes ?

The hazards of no hash but I understand how it allows you to use samples that sound like you remember. Memory is funny thing.

Yeah I have the newer samples that have some merging. I will replace the new Gorf samples with the older Pre 125u2. If you see any other sets you prefer just let me know. I am using all the enhanced versions from Twisty's (Retrocade and Gyrovision versions) but if you like the official ones or the older ones (like Wizard of Wor has current and older) just let me know.

maxbeanz

@riverstorm Not sure I understood you. I just wondered if the Gorf samples you are using (Gorf (0.125u2 & Newer))' are actually compatible with mame2003plus ? If you look inside the zip, 11 of the files are 0 bytes. Is it corrupted ?

dankcushions

@maxbeanz yes. no mame version is going to be able to do anything with a sample file of 0 bytes :)

i just downloaded the same file as you and all the files had sizes. try redownloading.

maxbeanz

@dankcushions There are 98 files in the 'Gorf (0.125u2 & Newer)' from Twisty's. 11 are 0 bytes.

I think he was talking about "Gorf (0.125u2 & Newer)" has some zero byte ROMs and "Gorf (0.125u1 & Older)" has none. When I built the DAT it was with the newer set and should have been the older set to work with 0.78.

I am not sure but I think it is intentional (no longer needed) maybe the newer MAME versions are using dumped working ROMs so they no longer need those samples. Either way the older set is for 0.78, it has the same samples and they aren't zero byte.

maxbeanz

@riverstorm The older Gorf samples are OK apart from the 'emperor' sample. It's 1kb and doesn't play anything. Not sure if it's supposed to be like that ?

dankcushions

sorry, yes, i rechecked and i have the same 8 files at 0 bytes. perhaps they haven't been recorded, or aren't used by the game, i don't know. there are no checksums or 'official' mame samples. we just work with what people have recorded and circulated.

i've began to lose the thread of this conversation - can't you just install the samples and see if they work in mame2003plus? all it will care about are the file names.

There's only two choices either the newer 0 byte or the older 188 byte sample. If you have another sample we can drop that one in place?

markwkidd

@mediamogul these folks are trying to get some Gorf samples sorted out. Do you know anything about this emperor sample?

Hey Dank, a double recheck, it's actually 11 just to verify we are looking at the same sample! ;)

Gorf samples update -- the ancient .sam MAME sample pack from Twisty's does contain a non-0 emperor audio clip: http://samples.mameworld.info/sam.htm

TL/DR: You can download emperor.wav here: https://www.dropbox.com/s/l4uk3s6d454ksrq/emperor.WAV?dl=0

I don't plan to host that wav forever in Dropbox but it can hang out there for a while until someone comes up with a more permanent location.

If SAM format samples comes up again
There is a Windows utility to convert between SAM and .WAV: http://samples.mameworld.info/Utilities.htm

When I run the executable in Win7x64 it complains that I must use 32-bit Windows

I can successfully compile the included source via MSYS2 in Win7x64 but samtowav crashes with a segmentation fault unless you specify the name of the input file on the commandline when you execute -- in this case it was samtowav EMPEROR.SAM

That did the trick, as far as I know.

Sorry to come in so late. Trying to whip my yard into shape. The 'emperor' sample can also be found here as well. It's impossible to know the longevity of sampleswap.org and no one should have to host the file forever on their own cloud storage. Ideally, the file could be included with it's brethren in a more appropriate location before it's lost.

Riverstorm

Thanks guys are they the same sample? Sampleswap wants you to create an account to download so I just grabbed the one Mark posted. Is this the sample you were thinking @maxbeanz is correct?

Riverstorm

Media when you're done I could use a good raking over this way too but it might be a few more weeks as we are getting 3 to 5 in snow today...in April...sheesh...the Canadians need to take that stuff back north for spring already! ;)

Wow, that's wild. I live in South Carolina and we haven't even had that much in the winter since 1986. It's really sad to see the kids try to make a snowman out of the amount we get at any one time. When they're done, they've rolled the yard clean and the body is still mostly mud and gravel.
