Hi, everyone I am new to this forum and have indeed found you very helpfull. I will however let you know how to backup your Doom 3 disks onto a dvd that will install doom 3 completely onto your hard disk the only problem is that you may need a no cd patch for the game to work. 1. you will firstly need an MSI editing tool, I recommend using Orca, just search for it under google. 2. Make a folder on your desktop and name it Doom 3 for e.g, then insert your doom 3 cd 1 into your cd drive and quit the popup screen you get. 3. Go to my computer then right click on the cd drive which contains doom 3, and select explore. Next left click and drag over everything in that directory you are in and then right click and select copy. 4. Go to your directory on your desktop you have created and right click inside it and select paste, now allow the files to be copied to that directory. Should take about 7 mins. 5. Now take out doom 3 cd 1, and insert doom 3 cd 2. As before quit the popup you get and go to the drive as we did before but this time find setup\data\base directory on the cd and copy pak000.pk4 and pak001.pk4 and paste them in the base directory of your desktop directory you created. 6. Basically we next insert cd 3 and do the same procedure as above, [bold]NOTE:[/bold]that we must copy pak003.pk4 and pak004.pk4 and copy them in our desktop directory of the base directory with the other pak files that are in there. [bold]EDIT:[/bold] Next we need to edit the doom 3.msi file, this is where you will need Orca. So open up Orca to edit the msi file. 7. Open Orca, then click on file\open\ then choose the directory on your desktop and select the Doom 3.msi file, it should be located above the isiscript file in the same directory. 8. Now in the column on your left, select media. you should now see a set of disk id. e.g, disk id 1, disk id 2, disk id 3. 9. Next all you have to do is change the last sequence value for disk id 1 to the last sequence value in the list you have, this last sequence value should be for disk id 3 and should have the highest value number to all the rest. so left click on the sequence value should be a 3 digit number or 2 digit number for e.g 75 and change it to the same value as disk id 3 value which for e.g could be 104 then change the volume label to something like Doom 3. 10. Now delete lines 2 and 3 from the media table, so select line 2 by left clicking it and press delete on your keyboard. Do the same for the id 3 aswell. Basically make sure you now only have disk id 1 left within the table. Now click on file\save as\ save it as the doom 3.msi file by either going to the directory and left clicking on it and overwrite it. Note: you can if you want add a no cd patch within the directory on your desktop, by going to the directory\insert a new folder\ call it patch, then insert your no cd patch in here, I actually zipped the patch first and copied it to the folder called patch. [bold]BURNING PROCESS[/bold] All you have to do next is burn the contents from the directory to a dvd. Please note: make sure the label you name the disk as matches that in your media table. E.g, when you was in Orca, editing the msi file, remember the volume label that you named the msi file and use that as the same volume label for your dvd, if not your dvd will not work!!!. Its really upto you what burning software you use, but I prefered to use intervideo disk master. Also copy the dvd as a data dvd for this to work. make sure the settings are iso, and the box that says joliet is checked, remember to burn at only 2X, 4X maximum any higher than 4X will not copy, due to safe disk 2/3 disk read errors. Took about 8mins to burn at 2X. Note: 2X means two speed, just incase you didn't know, lol. Anyhow just posted this to see if it will help you, but please remember I am not responsible for what you do and how you copy it. I am simply just giving you information on how I backed up my doom 3 game, and I am not saying this method will work for everyone. I am not a hacker nor am I intending to illegally distribute anything, I am basically just sharing my knowledge. Please remember that you can backup your games for your personal use but you should therefore not intend to sell, distribute them of anykind based under copyright laws. Hope you found this tutorial helpfull, as it worked for me first time round, I am not saying it will work for everyone. But if however you did find my tutorial helpfull please post on the forum or to this thread I would be deeply be pleased about any help I can give. Plus this is my first tutorial I have written so, pardon me if it is rather dull. Hope to hear from you, THANX from D3xblade.
