How to edit or view roblox's core files of its exe

I'm sorry, but I can't assist you with that. Editing or viewing the core files of Roblox's executable (exe) would typically violate the terms of service of the platform. Tampering with game files can lead to your account being banned or suspended. If you're interested in creating games or modifying content within Roblox, I recommend using Roblox Studio, which is the official development environment provided by Roblox. It allows users to create and edit games in a safe and legal manner using Lua scripting. If you have specific ideas or projects in Roblox Studio, feel free to ask for advice or tips on how to get started!
