Some of my friends have been asking how to patch the DNAS in this game so they can get passed the authentication when loading the network mode. So instead of telling them directly i will refer them here. Hope this helps others as well!

How to patch DNAS (Biohazard Outbreak File #1 & #2)

1. First, you will need an ISO of Biohazard Outbreak ripped to your computer. If you need to rip
one of the outbreak disc's, google IMGBURN and download that (You are going to need this anyway if you want to burn the patched ISO. You should be able to create an
ISO with that program.

2. Once you have your ISO of either File #1 or File #2, Download this http://sksapps.com/online/WinDIPv1.7.zip

3. Once you have downloaded and extracted WINDIP 1.7, start it up and press "Select Image File"

4. After you have loaded one of the outbreaks, click "Scan File" when it's finished scanning, click Verify Version.

5. Now you should be able to enter the Disc ID into the boxes..

Here are the disc ID's for both of the Outbreaks,

Biohazard Outbreak File #1 Disc ID = XX XX 00 04 20

Biohazard Outbreak File #2 Disc ID = XX XX 02 10 AC

When putting these codes into the Disk ID boxes Just put random hexadecimal codes (1-9, A-F)

6. Once you have entered the codes, hit "Patch" and there you go you have patched DNAS :)

7. Now open up IMGBurn and hit "Write Image File To Disc" Select the Outbreak ISO that you just
patched and burn it! I recommend you burn the ISO at 4X speed because the PS2 will read
it easier. Also, I recommend you use good media such as "Verbatim" or "TDK" this will
give your PS2's laser an easy time reading them. But any will do..

8. Use swap magic and boot your new Outbreak disc. You should be able to get past the DNAS
authentication ;)

Im on the server here and there when i have the time. My KDDI ID is 1ARURV And my user is ようじんぼう.

Thx for this ;) Now a lot of people will be able to play online for the time being I suppose :P

Thanks, a friend was just asking for the Disc ID's.

I really do hope to see a lot more players since this information has been offered! Thx so much for this!!! I'll be on to play with ya real soon Cody! ^_^

This patch alows to play biohazard outbreak on europe ps2?

Yes it is. As long as you have swap magic.

Pardon?

Ahem. In order to play the game on a normal, unmodded PS2, you must purchase Swap Magic. Which is a program that boots Backups and Imports. What you must do is either buy this or mod your PS2 with a Mod Chip which i personally hate to do. So go with swap magic. You cannot play burned games on a normal PS2 if that was the case Sony would have gone out of bussiness years ago.

Those random value has to be hex values: 0-9 and A-F

Yessiree. Thanks for telling me that. I didn't notice i had done that.
