Sep 24, 2009  Missing Intel IMA ADPCM (11) VLC needs no Codec usually so use it as a backup, when it asks to take over file associations just say no. Hope this helps. Rob - Bicycle - Mark Twain said it right. Did this solve your problem? Sorry this didn't help. Thanks for marking this as the answer.

Feedback 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). Save2pc ultimate license key. You’ll have to find those on the net.

Codec

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! Feedback 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;).

Feedback 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.
