Picked Upload! This is a picked upload! It showcases some of the best talent and creativity available on MTS and in the community.
Custom Sims 2 Launcher that includes some quality of life changes, customization, more modern in-game graphics, a real fix for Firstborn Syndrome, and more!

This is a custom launcher for The Sims 2 that includes a lot of new customization and modding options. You can enable Rich Presence so your friends on Discord can see what you're up to, play in borderless mode to easily alt tab, change the price of the design tool to your liking, among other things.

All features below are modifiable via a Settings application that will launch automatically the first time you boot Sims2RPC.

Better Live Mode Camera
Like in The Sims 3, better, less restrictive camera rotation controls.

Discord Rich Presence
If you have Discord open, it shows what you're up to on TS2 on your status! (Live mode, who you're playing as, how much money you have, what neighborhood you're in, buy mode, build mode, etc.)

First-born Syndrome Fix
Perhaps one of the oldest bugs in the game, the random sequence for genetics in The Sims 2 is not properly randomized, this leads to your first born, second born, third born, etc. babies in your play session to always come out the same. Up until now, we've had to do workarounds like going into CAS and hitting randomization a few times, no more! Included in this launcher is a file that gets injected into Sims 2, and via memory editing it alters the function inside of the game's executable that advances this broken random sequence to be actually completely random! Now babies will always be different and varied, without you having to do anything weird!
In-depth explanation

Borderless Mode
Quick alt tabbing!

Improved Graphics
Higher resolution shadows and lot imposters can be toggled via the settings.

No more "Too many Iterations"
The SimAntics too many iterations limit has been bumped up, so this error should no longer be an issue.

Design Tool custom pricing
No more $15 recolors, unless that's what you want!

EP Choosing
Experimental feature that allows you to disable EPs from the launcher, allowing you to, for example, create CAS lots.

The installer version of the launcher will automatically download the latest version and locate your Sims 2 folder with just one click, then prompt you to create shortcuts and launch Sims2RPC. If it's your first time booting the launcher, you will also be prompted to configure it to your liking.

Installation (Manual version):
  1. Extract the contents of the zip file in your Mansion & Garden TSBin folder, located in "The Sims 2 Ultimate Collection\Fun with Pets\SP9\TSBin" for Ultimate Collection users or "The Sims 2 Mansion and Garden Stuff\TSBin" for disc uesrs.
  2. Every time you want to play with these fixes, launch the game via Sims2RPC.exe.

Usage and Configuration:
  1. Every time you want to play with these fixes, or every time you want to play Sims 2, launch the game via Sims2RPC.exe.
  2. You can configure the features by opening the Sims2RPCSettings.exe application.
  3. You can test the Firstborn Syndrome fix in-game by going into CAS or a family and playing with genetics/having a baby, babies should now always be completely random, no need to roll the pacifier or generate random Sims anymore!
  4. You can edit the config.txt file to completely customize the text displayed on Discord Rich Presence!
  5. You can make a shortcut to Sims2RPC with command line parameters and they will get passed to The Sims 2.

Troubleshooting and FAQ:
  1. Enhanced imposter quality might cause crashes for some people. If this is the cause for you, try switching to Medium instead.
  2. If the launcher crashes, you might need to download the latest C++ Package from Microsoft:
  3. If the updater or settings app crashes, you might need to download the latest .NET Framework from Microsoft:
  4. If resolution looks stretched/too low or weird in any way: Fix instructions
  5. Make sure the launcher is in TSBin, and not in its own folder.
  6. You can try repairing the launcher with Sims2RPCUpdater.exe.
  7. You can download updates manually from and replace your RPC files with those.

hey thank you so much for this! i was under the impression this mod was not doing anything in my game because the lot imposters and shadow were not working, but i enabled all the other functions and they seem to be fine... it's not crashing or anything either, just keeping the same old lot imposters. i scrolled your tumblr and the comments here and it doesn't seem like anyone had the same issue? i used the maligned graphicsrulesmaker to fix my resolution, but i'm not sure that could have any impact here (throwing it out there just in case)

Yeah, totally same. And yeah, I used Graphics Rules Maker too

UPD: it works - one needs to just regenerate them by moving something in build mode and saving.
Anyway, it didn't fix the annoying roof artifact, so I got back to classic. As for shadows, hard to say yet

If you are having the issue of windows defender saying that rpc has a virus, then you need to open windows defender. click manage settings, and then turn off real-time protection.

After doing that, add the RPC executable to the exceptions list and turn real-time protection back on!

I have been having problems with simsRPC that I never had before (I didn't play for a while) neither the configuration nor the game itself opens, and when I update nothing changes.
all I notice is that it leaves me a file that says the updater is being used by another process, what do I do?

It looks like the manual installer file hare is infected with some virus and I keep gettng alerts about that issue.I've dicovered that the issue might be with MSE no longert updating and the last time it updated left it broken with a faulty update.It looks like anybody still using MSE will have to look for a replacement virus protection and it's going to be a free one for me.MSE last issued and update over a month ago which might've been faulty.
It looks like MSE had a faulty update and I've tried ton download the manual installer for RPC and it downloaded fine with MSE realtime protection enabled and MSE scan detected nothing except that the file was clean.

I hardly comment on this site, I just wanted to say thanks to LazyDuchess for creating this and opening up a new way of modding Sims 2, I hope work on this continues!

I unfortunately have some problems to report, I've experienced longer loading times (up to 2x as long) and highly unstable gameplay on lots, to the point of crashing as soon as I click to play on a lot. The only stable experience has been with one of the maxis lots in Strangetown. I have an absolute ton of CC - about 8 gigs worth collected over 15 years or so, so I'm guessing that may be why? Or perhaps windows defender is still not liking the way the .exe runs.

For those reporting virus alerts etc, it's always good to be cautious, but worth bearing in mind that false positives are understandable for this. The launcher/exe is designed to alter another program already running in memory (Sims 2) and this can look very suspect to an anti-virus, as it's how malicious things often work as well.

Hey guys, has anyone had an issue with getting the game to work after uninstalling the launcher? I originally installed it using the auto-install version, and then had to uninstall it due to issues with my antivirus. Unfortunately now I can't launch the game no matter what I try. I keep getting this error message that some files were corrupted. I don't understand what went wrong, but just wanted to warn others that if you use the auto-installer and then uninstall it, your game may not launch anymore... I'm not sure what caused it but I'm super sad Anyone had this happen?
