!!WARNING!! Anti-Cheat Games require Kernel Drivers to be disabled!

If you use Steam Deck Tools with Kernel Drivers enabled, you can be banned from online games with anti-cheat functionality! To disable this, follow the steps below (or you can skip to it here, Disabling Kernel Drivers for Anti-Cheat)

DO NOT use on anything besides a Steam Deck

This software accesses kernel level functions from memory addresses, specific to the Steam Deck. This overlay and none of these programs are meant to be used on any other hardware besides the SteamDeck. Attempting to do so could result in a potential brick of your hardware if it is NOT a SteamDeck!

To use this app, make sure that you have a supported BIOS(you will get a prompt letting you know if your version is not compatible). Below are the current compatible BIOS versions:

You can check your version by holding Volume + & Power at startup, then go to Setup Utility and it's at the top of the Main page

If you want to upgrade your BIOS, please make sure that SteamOS is fully up to date. NOTE: there is a manual upgrade process using a BIOS flasher in Windows(there also is a method in SteamOS/Linux), while I have used it myself, it is not recommended due to risk involved and will not be covered here.
