Antipiracy issue?

I'm trying to play Taiko no Tatsujin: Dororon! Youkai Daikessen!! on my DS, but whenever I start up the game the audio is very staticky and it's extremely annoying, making gameplay difficult.
I downloaded the ROM from this thread: http://forum.romulation.net/index.php?topic=44212.0

I'm using the latest Wood R4.
What can I do to fix this issue?

 

Use this version:

I don't know of any AP that affects the audio ???

 

@Aeither: That's the file I'm using.

 

Did you download the patched rom in the spoiler tag ?..

 

I'm using the patched file, yes.

 

Open your ROM with a hex-editor like HxD portable

http://www.pendriveapps.com/hxd-portable-hex-editor

You see on that image on the left side, they is a , offset (h) scoll down to 00004420 in offset (h)

And if you see this in the data you know for sure if it is patched.

Code:

0x00004420
24 00 9F E5 00 10 90 E5 20 20 9F E5 02 00 51 E1
1C 10 9F 05 08 10 80 05 48 11 80 05 14 10 9F 05
A8 10 80 05 E8 11 80 05 1E FF 2F E1 5C 8E 0D 02
4F 03 5F E1 37 B3 AA 36 6A E0 AA 36

0x000049F8
88 FE FF EA

This is the fix for this game, Don't know if the AP is the sound though.

If not you can copy/paste that data over the over data by at start of the offset address ^ .

 

Maybe there is a problem with Wood R4 applying the bypass and there is already a patch on it...
Try a clean version.

 

This error happens both on patched and unpatched files of the game.
