Roblox Auto Patcher

Automatically and easily patch 2019 and below Roblox Player, Studio and RCC.

This program uses the safest way of patching, by simply replacing the signing certificates and replacing all roblox.com urls with one of your choice. This avoids disabling trust check, and signing outright.

Warnings & Notices

You will have to put the signing keys in certain coreguis/corescripts/join scripts, and files. If you didn't already know this, you probably shouldn't be using this program.

This program should work perfectly fine for 2017 through 2019 clients. Other versions may require additional patches, mainly >2014 clients.

This program does not support iOS, and Android patching. Sadly, you will have to figure out how todo these on your own.
