The best I can do is unzip all the roms and see if WinZip runs into any errors

As you say CMP runs to completion - this step of extracting doesnt seem needed..

So while "Rebuilding" an older MAME set (source ZIP) to newer MAME set (dest. ZIP)

You are basically loosing control over you PC, while CMP is doing the task..

Not only while CMP is "Rebuilding" do you loose control of PC.
But you don't even regain control after CMP has completed.

That sum it up ?

Yes, that sums it up.

One more comment and a question regarding the long rebuild time and the Windows lockup.

For the rebuild, I specified the source directory as one which included all the rom updates from 139 to 150. I specified the destination directory as my rom folder, but I'm not sure that was right. Since my rom folder contained non-merged sets, and the rebuild was creating split sets, should I have specified both folders as the source and an empty folder as the destination?

[oxyandy]

Actually for speed.. (which also means convenience)
it is so much better to take the 'latest dat' set the path to the 'old folder'

Use "Scanner" with all fix option ticked - untick "Ask before fixing"
And let CMP do it's thing.
Rebuilding from "Back-Up" folder afterward (& what ever update folders etc)
But slightly going off topic pointing this out

I forgot to add:
on win8 not only while CMP is "Rebuilding" do you loose control of PC.
But you don't even regain control after CMP has completed.
eeek that sounds awful, see I get it.

Many tnx to Roman,Oxy and Cobra for discussion
But Oxy explain me what problem have cmp under win8 ? Because me used win8.1 and not view problem with loose control of PC. Tnx

[oxyandy]

Hi oddi
Well I understand the problem, the effect it is having on his PC.
I have no idea why it is happening ?
Guess a badly written driver ...
I would use something like this:
https://www.slimwareutilities.com/slimdrivers.php
Check to see if any updates made any difference .. ?
Again - I am guessing.

Is good to hear from a win8 user who is not having any issue with CMP (YOU)
I have not ever tried win8 myself & have no plan to use it any time soon either

[oddi]

Tnx Oxy, me see @cobra have new very good hardware, my hardware is too new ( 1 month ago) -
Gigabyte f2a88xm-d3h / A8-6600k /8GB dddr3 /win8.1 x64. Me think cmp work different of differents hardware,, atm my cmp not randomly crashed, who know, time is see.

Well, no other person with Win 8.x did report such an effect yet.....and actually it sounds more like an OS issue....if it's a lengthy operation (where cmpro may take a lot of cpu time), you may want to monitor your cpu/mb temperature with a tool...or the general memory/cpu activity in task manager....Maybe other running tasks interfear...etc...etc...

[65Cobra427SC]

Thanks for the info everyone. I'll check a few things to see if it makes any difference, but in all honesty I don't update Mame all that often so my use of CMP is limited. But if I do happen to find what's causing the problem, I'll definitely report here. In the next couple days I'll try to disable multiple drivers and see what effect that has. If it eliminates the lockup, I'll narrow that down as well. Either way I'll fill you in.

[65Cobra427SC]

I disabled almost all the non-Microsoft services using the System Configuration tool (msconfig) and after running a rebuild and scan the lockup issue is gone. I don't plan to narrow down which service(s) were causing the problem because it would be too time consuming... it could be one, or a certain combination, and they're all necessary for one thing or another. But at least we know it's a third party driver causing the problem and I'll just disable them all before using CMPro.

[Roman]

Thanks for the feedback...however this method is a bit..erm...beyond what you'd expect.....

Haven't installed Windows 8.1 yet but other users did not come back with such a report....
I guess it's some service connected with powermanagement or background re-indexing or defragmentation....something like that....(however you got that on Win7, too....)

I remember some early Windows XP installs where the 3d screensaver killed everything :-)

[65Cobra427SC]

Understand. In my case, I'm very particular about what runs in the background so I periodically take the time to disable anything unnecessary, especially following a program installation. Of course that still leaves critical programs like Norton which I leave as is even though it can be notorious at times. But I clear out any snippets which run at startup for programs I don't use daily. However, I do have some items which the casual user doesn't, like VMware and drivers for a RAID Mirror of drive D: which isn't using the intel chipset. But if I happen to figure out exactly what's causing the problem, which I still may do at some point, I will definitely post it here.

[Roman]

thanks for the effort
