HAVING TROUBLE DOWNLOADING?

For users that are having problems downloading the large files that are on this site, broken downloads, slow downloads and so on, we highly recommend using a download manager that has resume capabilities. Below is the program I use.

http://www.freedownloadmanager.org/download.htm

Dispite the not so impressive name this program is one of the best download managers on the web and if you use it you will never have another problem downloading from this site, plus you dont have to add the download links manually, this program does it all for you even with the "Registered Only" downloads.

We are on a shared host so this problem is expected so just give this program a try and see how it goes. You can always uninstall it later.

Idle Accounts Will Be Deleted After 6 Months

We have installed an auto prune system for users that have not logged in within 6 months in an attempt to keep our userbase active.

If you have not logged into this site for a minimum of 6 months, your account will be deleted and you will need to create another one.

TOPIC: CHD file version

CHD file version 1 year 4 weeks ago #251

xfuture

I have used MAME for a bit but I am new to CHD files. I just started downloading some from this marvelous site when I realized the url says they are for MAME v143. Will these work with MAME v145? What's the difference? Do I need to redownload CHD files for each version of MAME? These files are large so I want to make sure I am downloading the correct ones. Thanks to anyone who can steer me in the right direction.

Hi xfuture and welcome to the site.

That number you see in the URL has nothing to do with the version of mame it is simply the sub category ID number for that particular category. It was just a coincidence that the number was close to the latest version of Mame.

For instance the end of the URL for Mame v4 CHD's is this 143-mame-chd-v4 and the end url for Amiga CD 32 is 172-amiga-cd32.

So you should have no problems running them. They are the latest versions.

Jeeze I hate feeling like such a noob but since I am I guess it's ok.

So I get almost done downloading the CHDs for v145 only half of page 9 and all of page 10 left when, bam they are all gone. Now MAME is at 146 and the CHDs are starting all over. So the CHDs I downloaded are specific to 145? They won't work on 146? Is it the same with ROMs? Everything is specific to the version of MAME?

If that's the case where can I finish the set or v145 since I am so close?

Don't panic, You should still be good to go. Keep the CHD's you have downloaded already and just wait until we get the CHD's back up and check the V5 directory to see which ones need to be converted to version 5 and use CHDMan to convert them.

Your v4 CHD's should still work in the latest Mame for the moment.

We removed all CHD's so we could upload whole new v5 CHD's which may have interrupted the download progress of some users.

Normally it would not be this confusing but when the CHD format changed that's when things got a bit hairy.

If you need help converting your CHD's let us know.
