Mame 130u1 CHD changes

Oh No! All Chd's need to be updated according to Mamedev.  Can anyone make a batch file to do this?

Thanks for your help,

Here's what I've made: Be sure to change the first line to point to the folder that contains the chd folders...my chd folders were all in the 'rom' folder...
And change the line "c:\mame\chdman" to point to your chdman exe. AND USE AT YOUR OWN RISK!

dir /b /s /A:D c:\mame\roms >list.txt
FOR /F "tokens=1" %%A IN (list.txt) do (
   dir /s /b %%A\*.chd > filelist.txt
   FOR /F "tokens=1" %%f IN (filelist.txt)   do (
      c:\mame\chdman -update %%f %%f_n
      del %%f
      move %%f_n %%f
   )
)

Just keep in mind, I don't think there is a way to 'go back' once you've updated your CHD files - so those who enjoy a certain functionality or speed of a pre-0.130 build might want to only update when the game is needed (or tuck the old CHD's somewhere "in case")

Does MK's HS.diff file also eliminate the new error for CHD's from appearing?  If so,  I won't even bother updating.

Yep...no error messages.

Hi All,

Do all the CHD's including the LD's need to be updated from Mame 130?

If so, what is the best way to convert all the CHD's? Is it by using a batch file? or are there other options?

If the batch file is the only option, Is there a batch file which someone can provide that:

Reads the original CHD's from one directory (without modifying the CDS's), and converts the CHD's to a destination directory?

BTW. My CHD are in root subdirectories and not in the root rom folder itself.

Any feedback is kindly appreciated,

Dariusz
