clrmame Discussion / Using a bunch of cores on CHD verification?

« on: 10 March 2024, 20:05 »

Hi Roman, is there a way to have cmpro use as many CPU cores as possible to run through its deep -verify check on a CHD scan?  I'd still like to finish off checking my collection (made it to the guitar freaks last time) but it seems to do one at a time and take a good amount of time.  I thought I saw an option for cores somewhere in my wanderings of your settings.  Thanks -

clrmame Discussion / Full Merge Mode

« on: 27 February 2024, 00:19 »

Hi Roman, troubleshooting all the CHD delta stuff and unavailables after audit recently, I switched from my long standing 'Normal Mode' to 'Hash Collision Name' for the Full Merge Mode to see if that would help on some rebuilds.  What's the difference and is it rare to use that mode vs 'Normal' or should I?

clrmame Discussion / CHDMAN producing damaged delta CHDs on a few sets.

« on: 23 February 2024, 00:34 »

Been looking at this for a couple of days brought on by an audit in the MAME UI (F1) and the available filter.  Shows 14 damaged delta CHDs that can't be -verify or -info'ed with chdman. Before I posted at mametesters I was hoping for a confirmation here, note that clrmame doesn't flag these w/ default settings.  Possible commonality? CHDs marked as 'Bad Dump'.

Current tip of tree chdman.exe (or release .262) is producing some delta chds that will error on run with 'CHD ERROR: Decompression error'. Resulting in machine placement into unavailable filter folder in MAME UI.

One such example is the child/clone photoply_sprt_xt_2004_sp_u.chd in Photo Play Spirit Xtreme (Spanish) / photopsxsp

Steps to repro:
1. Use full merged storage method.
2. Place the two Photo Play Spirit Xtreme (Spanish) CHDs into their appropriate directory:
"C:\MAME\Roms\photopsxsp\photoply_sprt_xt_2004_sp_u.chd"
"C:\MAME\Roms\photopsxsp\photoply_sprt_xt_2004_sp.chd"

7,283,106,173 photoply_sprt_xt_2004_sp.chd
3,427,733,716 photoply_sprt_xt_2004_sp_u.chd

3. Launch MAME.exe and do an audit with F1 from the UI.
4. Confirm Photo Play Spirit Xtreme (Spanish) is not present in the Unavailable filter/folder.
5. Convert the child CHD to a delta w/ clrmamepro or manually.
6. New child CHD gets cut down to size to:

1,977,511,281 photoply_sprt_xt_2004_sp_u.chd

7. Attempt to verify this chd:
\MAME\ROMs\photopsxsp>chdman verify -i photoply_sprt_xt_2004_sp_u.chd -ip photoply_sprt_xt_2004_sp.chd
chdman - MAME Compressed Hunks of Data (CHD) manager 0.262 (mame0262-152-g0636e54bb60)
Error opening CHD file (photoply_sprt_xt_2004_sp_u.chd): Decompression error
Fatal error occurred: 1

8. Run audit in MAME's UI with F1.
9. Observe Photo Play is now in the unavailable filter/folder due to the error.
10. A normal run with clrmamepro does not find this.

clrmame Discussion / Delta CHDs new feature.

« on: 21 October 2023, 17:55 »

Hi Roman, I assume you've seen:
https://github.com/mamedev/mame/commit/d1172bf710f2a7b1777ed7687f5ba65748d90ee9

This could lead to significant savings on child CHDs becoming deltas of their parents. Have you got your mind around how to support it? I'm not sure how to produce one of these deltas, but a guide might be nice for the potential space savings.

clrmame Discussion / Exclude a whole driver?

« on: 24 August 2022, 17:18 »

Hi Roman, you probably saw what happened today w/ kpython2. I've never had to look for it but does clrmame have a way to 'exclude' a driver's machines?  Could we say run everything as normal (scanner / rebuilder) but ignore all kpython2 games?  Cheers -

clrmame Discussion / Help req: CHD errors and renaming reqs.

« on: 18 January 2020, 19:10 »

Hi Roman, I've outgrown my NVME 2TB SSD which I was keeping a full set of MAME on w/ CHDs.  So I've moved the CHDs to a second SATA SSD.  I'm trying to do this for rompath:
c:\o\games\mame\roms
d:\chds

CHDs are stored in d:\chds\setname\*.chd structure.

I've added those to clrmame in settings rom-path (and mame.ini of course).
Mame plays fine and can find the CHDs, no problem there.

When I audit with clrmame I am getting a bunch of wrong name messages that I never did before, here's a sample:
wrong name: D:\CHDs\area51mx [wrong: D:\CHDs\area51mx] [right: a51mxr3k] [not fixed]
wrong name: D:\CHDs\area51ta [wrong: D:\CHDs\area51ta] [right: area51t] [not fixed]
wrong name: D:\CHDs\blitz [wrong: D:\CHDs\blitz] [right: blitz11] [not fixed]
wrong name: D:\CHDs\bm2ndmix [wrong: D:\CHDs\bm2ndmix] [right: bm2ndmxa] [not fixed]
wrong name: D:\CHDs\bmcompmx [wrong: D:\CHDs\bmcompmx] [right: hmcompmx] [not fixed]

Then I get the following messages referencing a wrong SysDefPath and clrmame wanting to put the CHDs back to their prior location it seems:
2 Spicy [folder: 2spicy]
wrong SysDefPath: 2spicy [wrong: D:\CHDs\] [right: C:\O\Games\MAME\ROMs\]
Area 51: Site 4 (HD Rev 2.01, September 7, 1998) [folder: a51site4]
wrong SysDefPath: a51site4 [wrong: D:\CHDs\] [right: C:\O\Games\MAME\ROMs\]

So where in clrmame can I re-set the sysdefpath for the CHDs to go to the new d:\CHDs location and what is happening w/ the renaming requests for about these 30 CHDs?  Thanks!

clrmame Discussion / Wonder if clrmame can combine roms for MAME / PinMAME in two locations

« on: 07 November 2019, 18:21 »

Hi Roman, I'm getting into Visual Pinball again after 6 years, laugh.  I'm looking at clrmame to help with ROM usage, I wonder if it can keep unique pinmame roms in one location and leave mame roms used in both in another.  To explain:

c:\mame\roms
c:\vp\roms

\mame\roms has a lot of the pinmame roms already, I want that to remain where it is so I get a perfect result w/ a scan of mame.exe.
\vp\roms is missing about half of vpmame.exe's supported roms.

I have rebuilt vpmame.exe's roms from \mame\roms into \vp\roms.  So I now have of course unwanted duplication between the two directories.  I can easily have vpmame use its ROM paths to draw from \mame\roms and \vp\roms.

So the question.  Can I have clrmame somehow create *unique* to pinmame roms in the \vp\roms directory while also recognizing the shared roms in \mame\roms so I can get a 100% scan result for pinmame between the two directories.  Does that make sense?
