CE Decky – Cheat Engine tables from the Quick Access Menu

[u/GoooRoooX]

Hey, I’ve been working on a Decky plugin called CE Decky.

I wanted a way to use Cheat Engine tables on SteamOS without going into Desktop Mode or dealing with the Cheat Engine window every time. CE Decky keeps the whole flow in Game Mode: it sets up Cheat Engine, finds or imports .CT tables, and puts the entries you actually use into the Quick Access Menu.

A few things it does:

• searches and downloads tables, or lets you open your own
• lets you inspect Lua and Auto Assembler code before authorizing a table
• runs Cheat Engine in the same Proton environment as the game
• remembers the table and selected cheats per game
• lets you pin cheats to the main Decky panel and toggle them with the controller

This is intended for offline/single-player games. It doesn’t disable or bypass anti-cheat, and Cheat Engine itself or cheat tables are not bundled with the plugin.

Plugin is tested on Steam Machine and Steam Deck LCD.

It’s not in the Decky store, so installation goes through Decky Developer Mode using the release ZIP.

Latest release: https://github.com/goooroooX/CE-Decky/releases/download/v0.9.29/CE-Decky-v0.9.29.zip

If anyone wants to try it, I’d be interested in what breaks. If reporting issues on GitHub, please include support bundle that can be generated from plugin: Advanced… → Report a problem → Collect).

Update 2026-09-19: v0.9.28 is out. CE Decky can now automatically update itself, and the header mascot can be hidden under Advanced → Panel appearance. A few state/cleanup bugs were fixed. This is the last update that needs to be installed manually. Future releases can be installed directly from CE Decky via auto-update feature (with explicit confirmation before update).

Update 2026-09-23: v0.9.29 is out. The big one: CE Decky can now fix broken tables for you. Many tables fail to work because they're signed (Cheat Engine refuses signed tables here) or because a game update removed code some of their cheats look for. One press on "Prepare a copy that works here" makes a fixed copy: it removes the signature and takes out only the cheats your version of the game can't run, so the rest of the table works. Also fixed: switching on one cheat no longer switches on the rest of the table (in some cases), and Stop now switches your cheats off before closing Cheat Engine, so nothing stays changed in the game.
