There is such a code.
I find it and can change the instructions. Add't 10 but 1 or nothing. But I want to add this value to the table for editing. The problem is that to the x64 value of the address you need to add a negative dword from memory. Preferably simply announcing the symbol in the right place. But I can’t do it in any way. Without complications.

Now my code is like that

the instruction is at 7ffa535b4fd3
it's 7 bytes long, so the reference start is at 7ffa535b4fd3+7=7ffa535b4fda

the offset is fee75e0a, since the most significant bit is set the value needs to be extended. fee75e0awill become fffffffffee75e0a (it's a negative value, but you can just add it to the values for calculations and ignore overflow)

so, the reference + offset=7ffa535b4fda+fffffffffee75e0a =7FFA5242ADE4

you can use the lua command signExtend(0xfee75e0a,31) to help you with the extending of the value (31 designates that bit 31 is the most significant bit in the value so it won't extend when not needed)

The principle of compiling the transition is understandable to me. I just can’t understand how to create the desired design with minimal corrections. Neither in terms of Lua nor in part of the assembler. This should be done quite simply, without the introduction of additional functions and mathematics. But I can’t convey to the ASM to be already compiled there.

I will supplement. I decided the situation in this way. But I don't really like this solution. It should somehow be easier to gather at the stage of asm. From one digit transmitted from Lua. But I can’t do anything there.

readInteger can take a second parameter. If true, it reads the value as a signed 4-byte integer (i.e. sign-extends it automatically).

How I'd do it:

I thought that by transferring the address of the instructions I could collect the desired transition in the part of the ASM.

Your code is much better. It is much better read. The only negative is the search for a unique value. Any repeated signature will give an error. And with such a short search line, this option cannot be excluded.

Although it turned out almost the same. All the same, I am grateful for the hint how it could be done in other ways at the Lua level.

All clear. If at the moment there are no simple options, then at this time I will use the proposed solution from Lua.

Thanks everyone for your help.

Crap!! This is exactly what I was looking for. That's what I've been trying to do for a long time. What stopped me was the presence of an error when saving. I never tried to save in any way and try to execute. I thought that if there was an error, it wouldn’t work.

This is how it should have been done from the very beginning. And no pain.
