How do i get luau load in studio?

I would recommend using loadstring. It works almost the same as load but will also be better when the user inputs their text into the gui as it executes luau code in a string format.

loadstring(yourtextboxname.Text)

Put this inside of a script and i would recommend adding custom functions to make it compatable with more scripts. You can add the functions code in a string format as a variable and add it onto the loadstring when the user executes their script.

local functions = [[
function customfunction()
-- add the code to your function here. duplicate this function code onto a new line if you want to create a new function.
end
]]

loadstring(functions.."\n"..yourtextboxname.Text)

\n is used to creates a new line inside the string so users code doesnt stay on one line with the users script using the textbox.

Replace yourtextbox name with the name of the textbox in you're gui

Now we need to add it to the execute button!

local button = script.Parent

local functions = [[
function customfunction()
-- add the code to your function here. duplicate this function code onto a new line if you want to create a new function.
end
]]


button.MouseButton1Click:Connect(function()
loadstring(functions.."\n"..script.Parent.yourtextboxname.Text)
end)

Put this whole script inside execute button! Make sure its a script and not a localscript so the executor has serverside abilities!

Now you have made a simple roblox studio gui cheat. This can execute print and other functions but you may need to add more functions for support for more scripts.

The process is about the same as doing it on the client (without the packing bullcrap that they add to the client) since they use the same core engine source code. You can find it through cross references or a signature. A good place to look is the Luau source code, which can help you find potential areas where you can cross reference to find luau_load.

I'll wrap this up by saying that reverse engineering isn’t easy, and you're going to encounter incoherent code (typically making no sense because it's intended for a computer to read, not a human) that requires some patience. It can take a bit of time to dig through it all. Tools like Ghidra are great to start the reverse engineering process with Roblox Studio. It takes practice to get the hang of it, so don't get discouraged. Keep digging and refining your skills as you go. It's all about pattern recognition.
