ShadySimDeals is a darkly satirical The Sims 4 script mod. Household-member and unborn-Nooboo sales are available from phones and compatible computers.

Requirements

• The Sims 4 patch 1.125.59.1030 (the verified development patch).
• Lot 51 Core Library, version 1.43 or newer.
• Custom Content and Script Mods enabled in Game Options.

Installation and use

1. Close The Sims 4.
2. Install Lot 51 Core Library 1.43 or newer.
3. Copy ShadySimDeals.package and ShadySimDeals.ts4script into Documents\Electronic Arts\The Sims 4\Mods\ShadySimDeals.
4. Delete Documents\Electronic Arts\The Sims 4\localthumbcache.package.
5. Start the game and load a household.
6. Open a Sim's phone, or click a compatible computer and open ShadySimDeals.
7. Choose Liquidate a Family Asset or Monetize Future Family Growth.
8. Phone actions briefly animate in place. Computer actions route the Sim to the clicked computer and briefly use it.
9. Pick an eligible household member, review the offer, and confirm.

Eligible targets are on-lot household members from infant through elder. Newborn sales are deferred because native newborn carry could not be made reliable; newborns are excluded from the picker. The active Sim, pets, Sims at work or school, other off-lot Sims, already-sold Sims, and Sims involved in another transaction are also excluded. The unborn picker applies the same on-lot requirement.

The household-member offer starts with the target's age value. If the target is pregnant, the configured unborn value and multiple-offspring multiplier are added to the offer; the pregnancy remains with the transferred Sim. After confirmation, sellers and targets from toddler through elder enter one shared rabbit hole for 75 Sim minutes when selling an elder, 90 for toddler through child, or 120 for teen through adult. For an infant, the seller first uses the game's native pickup interaction; another carrier hands the infant to the seller. Only the seller is then registered in a 90-minute rabbit hole while the attached infant travels and disappears with them. Natural expiration returns only the seller, transfers the target to the hidden ShadySimDeals Holdings household, and then pays the active household. Cancellation or startup failure transfers nobody and pays nothing; if payment fails after transfer, the transfer is rolled back.

The unborn picker includes every eligible pregnant non-pet household member, including the active Sim. Its offer uses the pregnancy tracker's expected offspring count. After confirmation, the seller and selected pregnant Sim enter a rabbit hole for 90 Sim minutes for one expected offspring, 120 for twins, or 150 for triplets or more. If the seller is selected, that Sim enters alone. Natural expiration returns every participant, deposits one payment, and then clears the selected pregnancy. Cancellation or startup failure leaves both pregnancy and funds unchanged. Because the count API only reports the current expected count, the mod does not force early twin or triplet detection.

Successful sellers permanently receive Family Asset Liquidator plus the 12-hour Quarterly Profits, Fewer Mouths Happy moodlet. A sold household member permanently receives Outsourced by My Own Family plus the 24-hour Apparently, Love Had a Return Policy Sad moodlet. When another pregnant Sim's unborn Nooboo is sold, that Sim permanently receives Stork Claim Mysteriously Denied plus the 48-hour The Nursery Has Been Downsized Sad moodlet. A pregnant seller targeting themself receives only the seller consequences.

Custom artwork identifies the ShadySimDeals phone/computer category, both sale choices in pie menus, their active queue actions, and all sale traits and moodlets.

A sold household member loses 100 friendship with the seller. Their parents, children, siblings, and spouse lose 50 friendship with the seller, while other members remaining in the seller's household lose 25; a Sim in both groups receives only the stronger 50-point loss. When another pregnant Sim's unborn Nooboo is sold, their current friendship selects a complicit, regretful, or betrayed reaction that changes friendship by +10, -25, or -75. A pregnant seller targeting themself receives no relationship change.

Do not remove the mod while sold Sims remain in the holding household; recover them first or keep a backup of the save.

The permanent traits are normal save-managed Sim traits: saving preserves them, while exiting without saving restores the prior save state. Finish or cancel an active sale before saving and reloading because active sale callbacks and reservations remain session-local, and private rabbit-hole interactions are not persisted across reloads.

Current scope

This release intentionally omits trait-aware seller moodlets, outcome-specific pregnant-Sim moodlets, ghosts, delayed outcomes, forced early multiple-birth detection, observer reaction buffs, sentiments, and persistent grudges. See SPECS_CHECKLIST.md for detailed implementation status.

Build and test

Requirements are Python 3.7 for game-compatible bytecode and Python 3.12 with pytest for development tests.

py -3.12 -m pytest -q -p no:cacheprovider tests
py -3.12 build_mod.py

The build creates dist/ShadySimDeals.ts4script and dist/ShadySimDeals.package, including the English string table, custom DST5 icons compiled from the source PNGs, and Lot 51 phone/computer injection tuning.

To change an icon, replace its existing 256x256 8-bit RGBA PNG under icons/ and run the normal build. The vendored Microsoft DirectXTex converter automatically produces the temporary BC3/DST5 data; no manual conversion or generated icon folder is required.
