Does the Pokemon mod replace the Tetramon cards?

Depends which one you install. Extended TCGs - Pokemon TCG adds new packs behind a phone storefront and leaves Tetramon untouched. Texture-replacement mods are the ones that change existing card art. Running both is a reliable way to get conflicts, so pick one.

Why does F1 do nothing?

The F1 menu comes from the Configuration Manager plugin, not BepInEx itself. If the plugin is missing, or HideManagerGameObject is not enabled in the BepInEx config, the key will not respond.

My save hangs on loading after installing the mod. What now?

Usually an outdated texture-replacement mod that does not match 1.0, or a mismatched dependency version. Pull plugins out of BepInEx/plugins one at a time, and restore your backed-up save.

Do I need to reinstall BepInEx after every game update?

Normally no. Steam does not delete winhttp.dll from the game root; mods break because plugins have not caught up with the new build. Check the BepInEx log, then update the mod rather than reinstalling everything.

Can I get banned, or lose achievements?

No ban risk: the game is single-player with no VAC. Texture and added-pack mods usually leave achievements alone, but mods that change pull rates or auto-open packs may disable them, and their pages say so.

Pokemon Card Mod for TCG Card Shop Simulator (1.0)

Know which kind of mod you are installing

There are at least two different "Pokemon mods" on Nexus Mods, and they carry different risks. Check whether the author describes a replacement or an addition:

Type	Example	What you see in game	Dependencies
Texture replacement	Real TCG Overhaul and similar	Existing Tetramon card art is swapped for something else	BepInEx + TextureReplacer
Added card packs	Extended TCGs - Pokemon TCG (Nexus Mods 792)	A new Extended TCGs storefront on the phone with roughly 2,783 cards	BepInEx + Enhanced Prefab Loader + Phone Overhaul

Extended TCGs does not overwrite Tetramon; it adds a separate pack shop to the in-game phonePlayer-tested. That is why it is the safer option: it appends content instead of patching existing card prefabs.

Install one kind at a time

Texture replacements and added packs both touch card assets, and together they produce blank cards, missing shelf stock or saves that hang on load. Get the added packs stable first, then consider anything else.

Dependencies and versions

The game hit 1.0 in September 2026, and the plugin ecosystem still runs on BepInEx 5. Do not install BepInEx 6.

Component	Current build	Where to get it	Role
BepInExPack	5.4.2305 (Thunderstore)	Thunderstore or a preconfigured Nexus pack	Mod injection framework
Enhanced Prefab Loader	Per the mod page	Nexus Mods	Loads new card prefabs; ships an API and preloader
Phone Overhaul	Per the mod page	Nexus Mods	Extends the in-game phone with new storefronts
Extended TCGs - Pokemon TCG	Per the mod page	Nexus Mods 792	The Pokemon packs themselves

A preconfigured BepInEx 5.4.23.5 pack with Configuration Manager was updated on 29 September 2026Player-tested. Take that route if you want the F1 menu without adding the plugin separately.

Version numbers rot

The mod page lists the exact Enhanced Prefab Loader build it needs. Follow that page, not an older guide: every game update can raise the dependency floor.

Back up the save first

This is the step people skip and then regret. Close the game completely before touching any files.

Press Win + R, paste %USERPROFILE%\AppData\LocalLow\OPNeonGames\Card Shop Simulator\ and hit Enter.
Copy the entire folder to your desktop and rename it something like TCS_Backup_2026-11-04.
The saves are files such as savedGames_Release0.GD, where slot 0 is the autosave. Copy the whole folder, not a single slot.

Steam saves live under LocalLow in OPNeonGames\Card Shop Simulator, named savedGames_Release*.GDPlayer-tested.

The game supports Steam CloudOfficial. If cloud sync is on, close the game before restoring a backup and, if needed, switch off cloud sync for this title temporarily — otherwise the service can overwrite the save you just copied back in.

Step-by-step install

Note your build. Right-click the game in Steam → Properties → Installed Files. Confirm you are on 1.0 and write the build number down for later troubleshooting.
Install BepInEx. Extract the BepInExPack and drop the BepInEx folder, winhttp.dll and doorstop_config.ini next to Card Shop Simulator.exe. Not inside Card Shop Simulator_Data.
Launch once. Load into the main menu and quit. This generates BepInEx\config and BepInEx\plugins.
Add the dependencies. Merge the BepInEx folder from Enhanced Prefab Loader and Phone Overhaul into the game's BepInEx. Watch for BepInEx\BepInEx nesting — that is the classic mistake.
Add the card mod. Extract Extended TCGs - Pokemon TCG and merge it into BepInEx, keeping the plugins and card-art folders where the author put them.
Verify in game. Press F for the phone and order packs from the Extended TCGs store.

TCG Card Shop Simulator: a player and a customer at an in-store card table — Boot a normal save in the unmodded game first so you know the base install is healthy.

Skip Vortex for this one

Community reports say Vortex does not handle this game's BepInEx layout well and tends to put DLLs in the wrong place. Manual extraction into the game root is the reliable route.

Confirm it actually worked

Check these in order and stop at the first failure instead of stacking more mods on top:

Check	Healthy result	What a failure means
Game launches	Main menu, no black screen	BepInEx or a plugin version mismatch
BepInEx log	Plugin load entries in `BepInEx\LogOutput.log`	Plugin not loaded; check folder depth
F1 menu	Plugin configuration window opens	Configuration Manager missing, or its config flag is off
Phone	Extended TCGs entry appears	Missing dependency or a nested folder
Packs	Pokemon boosters can be ordered	Incomplete mod extraction; re-extract

If F1 does nothing, set HideManagerGameObject to true in BepInEx\config\BepInEx.cfgPlayer-tested and restart.

Troubleshooting

Symptom	Likely cause	Fix
Black screen or stuck on load	Missing dependency, version mismatch or leftover plugin	Empty plugins, boot with BepInEx alone, add back one at a time
No Extended TCGs on the phone	Nested folder or dependency not loaded	Check DLL depth under `BepInEx\plugins` and read the log
F1 does nothing	Configuration Manager not installed	Install it, or use the preconfigured BepInEx pack
Blank cards or pink textures	Wrong card-art path or TextureReplacer version	Reapply the card-art folders per the mod page
Save hangs, shelves do not load	Old texture-replacement mod against 1.0	Remove the plugin and restore your backup
Everything broke after an update	Plugins have not caught up with the new build	Wait for the author; do not keep reinstalling BepInEx

Troubleshoot in this order

Unmodded game runs → BepInEx loads → one dependency at a time → card mod last. Add three things at once and you will not know which one broke it.

Versions, achievements and risk

Steam lists the game as single-player with achievements and cloud saves, and there is no VACOfficial. Modding therefore carries no ban risk.

Achievements depend on the mod. Texture swaps and added packs normally leave them intact; mods that alter pull rates or automate pack opening can disable them, and their pages say so.

There is no official modding statement or stable mod API for this gamePlayer-tested. Every update can change plugin compatibility, so treat any version number in a guide as a starting point and the mod page's Requirements tab as the source of truth.

The Halloween update reworked bulk boxes and some economy values, so prices and stock in an older save may not match the current build. Confirm the save loads cleanly in the unmodded game before you add anything.
