Ive just installed a new game and when I launch it I get the an error message saying.
“There will be no voice or sound effects because the system does not support ADPCM files." reply


Read this tut:
Install Microsoft ADPCM Audio Codec, IMA ADPCM Audio Codec and all default codecs. reply

I’ve tried this solution. It didn’t work.

My guess is the directx versions wich they tested the games with (meaning OOOOLd versions) supported adpcm files. Maybe newer Dx vers. (8.0 - 9.0c) don’t come with a straight compatibility for this kind of ADPCM.

Note : I installed both MS ADPCM & MS IMA ADPCM codec drivers as Marco suggested in a thread some time ago. The annoying error msg is still there.

On my knees begging 4 help. reply


I installed both MS ADPCM & MS IMA ADPCM codec drivers too, but still the system does not support ADCPM files from many games (Chain, Come to see me tonight, Snow drop and others...)

If someone knows solutions, please share. reply



I tried the solution that you give and the message is still appearing.

Please someone give us the solution for this problem.

I want to play this game with sound reply


Ok, here we go.

Chances are you’ve installed WinXP SP2. The culprits are two “updated” ADPCM codecs (imaadp32.acm and msadp32.acm) located in C:\Windows\System32 and marked as versions 5.1.xxxx (for the novices, WinXP is WinNT 5.1). For some reason they won’t work with many Japanese games anymore.

You have to back up those “new” codecs (just rename them) and replace them with versions 5.0.xxxx from Win2000 (aka WinNT 5.0). You’ll have to find those on the net. Or you could simply try with the default codecs from your WinXP CD, it should work but be sure they’re not coming from a Service Pack. In any case, don’t try any version prior to 5.0.xxxx! reply


Thank you Mokkori =), I found the win 98 version of the files you saind and now my games work.
You can find them in
or here ( i rared them for you guys) reply



Thanks a lot.

That solution works perfectly.

Now i can play the games and also hear them crying.

Wow These is great

Thank a lot for your help. reply


THANK YOU so VERY much!!!!
Now I can really enjoy theese games :)
I Love You :P reply


Thank you guys I finally can play h games with voices :) yey. What Mokkori wrote is right that in WinXP files “imaadp32.acm” and “msadp32.acm” (which are in system32 folder) has to be replaced by older versions. Links added by Thankful doesnt work for me so i found them here:

Imaadp32.acm ==>

Msadp32.acm ==>

These are drivers from win98/95 ver. Anyway when I replaced only “Imaadp32.acm” the voices in H Games started working :). Oh and before i replaced them I installed the adpcm drivers “step by step” as Marco wrote in here

Enjoy the H Games ;). reply


Hm... I don´t know why, but It didn´t work with my machine... reply


Guys i have the same problem but i cant acces the files you linked. Could you put it up again or send it to my via email.

Thanks. reply


Yeah me too please. YouSendIt files are kept for 7 days and deleted when this period expires. reply


Just helping, I also found those files in the drivers of this sound card CMI8330.

MSADP32.ACM ver.

They work for me.
Thanks for pointing me in the right direction.
The link that says “Win 95/98/ME" reply


Great !!!
It Really Works.

Thank you !!!

Really Thank you. reply



I am running Windows 98 and get the message:
“There will be no voice or because the system does not support DirectSound. Do you wish to continue (Code = 1:0)"

I’ve tried the above, replacing the two driver files imaadp32.acm and Msadp32.acm. I tried this on a WinXP machine, and it worked. However, I don’t even see these two files on my my Win98 machine. What do I do? reply


What all of you are suffering is the “G-collections Sindrom” , G-Collection games needs the USA languaje version the IMAADP32.ACM file.If your version isn’t from USA, there’s a high chance that the game will complain about ADMPC at start.

Just make a search for that file and when you’ve found it, right click on it to check its propierties and check the Version tab, see?, You need to replace the file with an USA languaje equivalent.

For W95,98,98SE and ME the file is at C:\windows\system
and for 2000/XP is at
C:\windows\system32 reply


Great! Thank you!

I have Windows 2000, and I did not feel that it would be OK to use files from Windows 98. So, I replaced the file
imaadp32.acm, version 5.0.2195.6612, Russian
with the file from Windows 2000 English setup CD
imaadp32.acm, version 5.0.2134.1, English
and it solved the problem.

One last note, I had to unpack the file using a command like this:
expand imaadp32.ac_ imaadp32.acm reply


nice man thank you reply
