Long overdue update 07/07/2010: Sorry for not doing anything with this for the last two years, but I pretty much stopped playing The Sims 2 shortly after writing this program. I still don't have Vista or Win7, but luckily NickM406 has written a CAS! Switcher program that is being updated and works with XP, Vista and Win7:

So a big thanks to NickM406 for keeping the idea alive and supporting the operating systems I can't. Please switch to that program as I won't be doing anything more with this program. Thanks again to everyone that responded to my program and I hope those that could run it got some good use from it.


I originally wrote this program just for my own use, but I thought I would share it as a thanks to everyone on here!

This little program makes it easy to switch CAS! screens for The Sims 2 game. You can add two preview screenshots so you don't have to guess which file is which.

I use several CAS! screens and trying to remember which one was which was getting to be a pain. Also renaming and moving files manually was a hassle. This automates the process and if you add screenshots it also solves the problem of which CAS! screen you are switching to.

Requirements: Windows XP (should work in any version of Windows 98 or higher, but I've only tested it with Windows XP)

Update: 4-11-2008 - Some people may need the Visual Basic 5 runtime file "Msvbvm50.dll" for this to work if they don't already have this installed on their system. This can be downloaded from Microsoft at:

Installation: Just copy the program file and empty folder to your Sims 2 DOWNLOADS folder, usually located at:

C:\Documents and Settings\............\My Documents\EA Games\The Sims 2\Downloads

then copy (one at a time) a CAS! screen file (usally named CAS!.package) into the folder named CAS (or create a folder named CAS in DOWNLOADS if you didn't use the included one). Rename each file to whatever you want, keeping the extension ".package". I find naming the file after the creator with an added number is easiest. Then add the next, and so on.

Example: rename CAS!.package to Phaenoh01.package

You can add two screenshots for each CAS! screen. They must be JPG format, but can be any size. The program will shrink/expand them to fit. They must be named the same as the CAS! screen file, but with an "A" or "B" added to the name. You can use lower or upper case, it doesn't matter.

Example: Phaenoh01A.jpg and Phaenoh01B.jpg

I just use the screenshots for both rooms provided from the author, saving each with the added letter, A for the design room and B for the group photo room.

Thanks to all the people and users at for all the great stuff they've done! I hope this program will encourage more people to create their own CAS! screens and share them.

...Yes it will! 'CAS!' files can go into the Downloads directory as much as they work in the normal program files! (Which is very handy if you think about it)

...Back to the uplaod... :D

Thankyou for this tool! Now I can switch between my CAS Files I made to beat Phae, But never got round to perfecting them all the time when I got bored! wahoot!

Everyone: Glad someone is finding the program useful. It saves me a bit of time and effort, so thought I'd share it.

TickleOnTheTum: No, the program and CAS folder need to be in the Downloads folder. It also will not work if you put it in a sub-folder within the Downloads folder. Sorry, but I wanted to keep the program as small and simple as possible; plus that is where downloaded CAS!.package files need to be located, so it makes sense to put everything together. You can always create a shortcut to it and put the shortcut anywhere you like.

The program also doesn't have any install program or Windows Registry settings, so it can easily be deleted by just removing the program file and CAS folder (save your CAS backgrouunds somewhere first!). :D

Thanks for the free advertising. Somehow I missed this when it first posted. If I wasn't a one-CAS type person I'd totally download this. It looks so useful and easy to use!

Looks like some versions of Windows don't come with the Visual Basic 5 runtime, so you can download it free from Microsoft at:

You only need the file "Msvbvm50.dll", so you can just do a search online for that specific file if you don't want to install all the other files that are included in Microsoft's installer.

This should also work for Vista users, although I don't have that OS so can't check it out.

When I get a chance I'll rewrite this in C++ and replace the current version.

Great idea for a program, Sadly I cannot get it to work I am using windows Vista... I downloaded the dll, then after that I get this error:

*Folder named CAS is missing or not in proper location.Please copy or create a folder named CAS in your Sims 2 downloads folder, usually locked:... My Documents\EA Games\The Sims 2\Downloads*

Vista manages the files slightly different, here is what it looks like:

C:\Users\Test\Documents\EA Games\The Sims 2\Downloads\CAS
