/jp/ - Otaku Culture

Using the BGI tools, I've extracted the sprites from the MG release just fine, but I can't seem to do the same with the PS2 ISO. Here's what I've done so far :
- Switched to japanese locale
- Mounted the PS2 ISO (Daemon Tools). I've run it with a PS2 emulator, the game works all right.
- Got the NIPA tools from http://azuco.sumomo.ne.jp/archive/ps2higurashi_r070720_.zip
- Got the wnaspi32.dll from http://www.frogaspi.org/download/wnaspi32.dll
- Followed the instructions on http://www.nicovideo.jp/watch/sm1182329

I'm stuck at the extraction part : I typed "nipa /d 6:0:0", then it freezes during about 30 seconds and does nothing (see attached picture).

I tried various other things like "nipa /d6:0:0", "nipa /d06:00:00", but it gives me the same result.

Would anyone mind to help ?
