The Sims 3 - DVD9 to 2xDVD5

[SuppA-SnipA]

1 - make a folder for dvd 1 and dvd 2
2 - copy all the files from the dvd to dvd 1 folder,
3 - GameData\Shared\Packages\FullBuild2.package goes into dvd 2 folder, but u must keep this folder structure, so make a gamedata folder (in the dvd 2 folder), make a shared folder inside the gamedata folder, make a packages folder inside the shared folder, then drag FullBuild2.package to the shared folder. delete FullBuild2.package from the dvd 1 folder after!

4 - cut and paste NonPackaged, from dvd 1 folder to \gamedata\shared\ in the dvd 2 folder
5 - copy and paste the support folder from the dvd 1 folder to the dvd 2 folder (the root of dvd 2), dont delete support folder from dvd 1!
6 - autorun.inf from dvd 1 - modify to

[autorun]
icon=Sims3.ico

save it to the root of dvd 2 folder. (we've removed the action to launch the setup, just so you know)

7 - skuversion, eauninsall.ico should also be in the root of dvd 2 folder
8 - add any extra stuff u need
9 - burn with udf format / make the image with udf format, label both discs as "Sims3"

the install step of the game is dvd 1 then 2, and thats it.

there are differences between copy and cut (duhhhh) so, when i say to cut, u CUT NOT COPY and vice versa
i have tested this exact method twice tonight, it has always worked
edit: this IS for 2 x dvd 5, thanks to omega59 for pointing that out
