UI Cheats vs MC Command Center

• Install UI Cheats if the thing that annoys you is typing. It replaces most of the cheat codes you would type with a click on the bar or counter you are already pointing at.
• Install MC Command Center if you want to change how the game behaves over time: NPC story progression, autonomy, what townies wear, how the population moves around.
• Install both if you want both of those things. They touch different parts of the game and are widely used together.

Neither one works on Xbox or PlayStation, and neither one survives a Sims 4 patch on its own. Both need a fresh build after the game updates.

UI Cheats Extension is a free mod by weerbesu, first released in June 2015 and still updated. The current build is v1.59.1, released on 27 August 2026 and built for game version 1.127.41. The download is a zip with two files in it, a package file and a script file, and both have to go in your Mods folder.

What it changes is the interface. Every cheat it adds is attached to something the game already draws on screen, so there is nothing new to open and nothing to configure:

• Left-click a needs bar to set that need to the point you clicked. Right-click it to type an exact value from -100 to 100.
• Left-click the money counter to gain §1,000. Right-click it to set household funds to an exact figure.
• Right-click a skill bar to pick a level, or add a skill that is not in the panel yet.
• Right-click a job icon to promote, demote, retire, change branch, or jump to any level of the current branch.
• Right-click a Sim in the Relationships panel to set friendship or romance anywhere from -100 to 100.
• Right-click a moodlet to remove it, and right-click the age bar to add or subtract days.

You do not need testingcheats for any of it. That requirement was dropped in v1.1, back in 2015. The full list runs to every panel in the game, including pack content, and it is on our page covering everything UI Cheats can change.

MC Command Center is a free mod by Deaderpool. His own site describes it as adding "greater control to your Sims 4 game experience and NPC story progression options" (deaderpool-mccc.com). The mod is free to download; the site carries a Patreon link for people who want to support it.

It is built in modules. The documentation lists mc_cmd_center as the main one, which everything else needs, and then a set of optional modules you add only if you want what they do: mc_career, mc_cas, mc_cheats, mc_cleaner, mc_clubs, mc_control, mc_dresser, mc_gedcom, mc_occult, mc_population, mc_pregnancy, mc_tuner, mc_woohoo and automation_scan. Between them they cover careers, Create a Sim body settings, cheat commands, club story progression, limited control of NPC Sims, outfit rules, occult gameplay, moving homeless Sims into empty houses, and the autonomy of individual interactions.

You use it through menus rather than through the game's own panels. Click a computer or a Sim and pick the MC Command Center menu, or open the cheat console and type mccc or mc_settings. Installation looks much like UI Cheats: the files go in the Mods folder no more than one level deep, and script mods have to be enabled. Deaderpool publishes releases against particular game versions, and one release can cover more than one Sims 4 version.

There is some overlap, and it is smaller than people expect. MC Command Center includes an mc_cheats module that offers world-based and Sim-based cheat commands, and a career module, so a few of the things UI Cheats does by click also exist somewhere in MCCC's menus. What differs is the route to them. UI Cheats puts the change on the thing you are already looking at. MCCC asks you to open a menu, find the setting and read the options, which is slower for a one-off change and far better when you want a rule that applies from now on.

The other real difference is scope. UI Cheats edits the Sim or the household you have selected. MCCC's story progression modules act on Sims you are not playing, which is something UI Cheats never does.

This is the safest part of the answer, because the author of UI Cheats addressed it directly. His compatibility note says the mod only conflicts with other user interface mods that override the same resources, and that it does not conflict with other kinds of mod such as script mods and tuning mods. MC Command Center is a script mod, which is the category he names as safe, and the third-party guides we checked report the two running together without trouble.

It is worth knowing the failure mode anyway, because it is quiet. When two user interface mods do clash, the game reads the first one it finds and ignores the second, so the second mod simply does not work properly. Nothing crashes and nothing warns you. weerbesu also notes that unrelated game problems are unlikely to be caused by that kind of conflict, so if your game is misbehaving in some other way, this is not the first thing to suspect.

Either order works. What matters is doing them one at a time, with a full restart between, so a problem has only one possible cause.

A sensible sequence: get UI Cheats in first, because it is two files and you can prove it loaded in about thirty seconds. Right-click the notebook icon next to the phone icon and the installed version appears, or type ui_cheats.mod_versionCopy in the cheat console while you are in Live mode. Once that checks out, add MC Command Center and restart again. Our install UI Cheats guide has the full sequence, including the two Game Options toggles and the Mods folder paths for Windows and macOS.

One rule applies to both mods and catches a lot of people: keep exactly one copy of each. Old versions, backups and renamed copies left in the Mods folder cause problems that look like conflicts and are not.

Neither mod runs on console. The Sims 4 on Xbox and PlayStation does not load script mods of any kind, and both of these ship a script file, so there is nothing to install. Console players get the built-in cheat console instead, which is covered on our page about console support.

Neither one replaces the cheat console entirely. Commands such as bb.moveobjects are not part of the UI Cheats feature list, so Build mode cheats are still typed, and so are pregnancy cheats, death cheats and the command that resets a stuck Sim.

And neither one survives a game patch by itself. weerbesu is blunt about this: if the interface breaks, glitches or freezes, it is a mismatch between your game version and your mod version, every time. Check the version history after an update, and if something is already broken, work through the fixes for UI Cheats not working in order.
