The voice ad-libs in the US version were disabled not removed.

Are you able to choose what audio to restore? I know there are some unique audio files that aren't in use in even the Japanese version.

Unfortunately I do not know how the speech files work. I restored ad-libs by changing a few values in the file to match the Japanese ones.

Just thought I spread this to biohaze but new people have made some big breakthroughs in emulating the OB severs for the Japanese versions of the game. The person working on them is saying in time anybody will be able to emulate their own OB severs, and he will be distribution the needed software to anyone.

check out his blog for more detailed information
http://devghostline.blogspot.com/ .... his progress is amazing it seems he has recoded a huge chunk of the outbreak online infrastructure, also all working on ps2 hardware with no modchips or anything like that.

Also in conjunction with that another person working along side this guy has successful translated the Japanese version of the OB games into English.

Capcom might have moved on and buried the OB series but these guys progress at least shows there is hope to continue online play for File 1, and 2. Maybe biohaze might be interested in getting in contact with this person and try to set up your own official biohaze outbreak sever, just a thought.

Picture of some of his amazing progress

Hope This works out in our favour :D

It looks like ghost removed his entire blog. I wonder what happened?

Possibly a Cease and Decist by Capcom.

Some1's made more progress! It's greedy, but I'd rather he worked on the Japanese version since the text can be edited and the characters can talk in it. It's the most complete version.
